如何使用C#创建Excel电子表格而不需要在运行代码的计算机上安装Excel？
当前回答
您可以使用此库创建格式良好的Excel文件：http://officehelper.codeplex.com/documentation参见以下示例：
using (ExcelHelper helper = new ExcelHelper(TEMPLATE_FILE_NAME, GENERATED_FILE_NAME))
{
helper.Direction = ExcelHelper.DirectionType.TOP_TO_DOWN;
helper.CurrentSheetName = "Sheet1";
helper.CurrentPosition = new CellRef("C3");
//the template xlsx should contains the named range "header"; use the command "insert"/"name".
helper.InsertRange("header");
//the template xlsx should contains the named range "sample1";
//inside this range you should have cells with these values:
//<name> , <value> and <comment>, which will be replaced by the values from the getSample()
CellRangeTemplate sample1 = helper.CreateCellRangeTemplate("sample1", new List<string> {"name", "value", "comment"});
helper.InsertRange(sample1, getSample());
//you could use here other named ranges to insert new cells and call InsertRange as many times you want,
//it will be copied one after another;
//even you can change direction or the current cell/sheet before you insert
//typically you put all your "template ranges" (the names) on the same sheet and then you just delete it
helper.DeleteSheet("Sheet3");
}
示例如下：
private IEnumerable<List<object>> getSample()
{
var random = new Random();
for (int loop = 0; loop < 3000; loop++)
{
yield return new List<object> {"test", DateTime.Now.AddDays(random.NextDouble()*100 - 50), loop};
}
}

好
也可以使用Aspose这样的第三方库。
此库的优点是它不需要在您的计算机上安装Excel，这在您的情况下是理想的。
您可以使用OLEDB创建和操作Excel文件。选中此项：使用OLEDB读写Excel。
典型示例：
using (OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\\temp\\test.xls;Extended Properties='Excel 8.0;HDR=Yes'"))
{
conn.Open();
OleDbCommand cmd = new OleDbCommand("CREATE TABLE [Sheet1] ([Column1] string, [Column2] string)", conn);
cmd.ExecuteNonQuery();
}

以下是创建Excel文件的最简单方法。
扩展名为.xlsx的Excel文件是包含.XML文件的压缩文件夹，但很复杂。
首先创建文件夹结构，如下所示-
public class CreateFileOrFolder
{
static void Main()
{
//
// https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/file-system/how-to-create-a-file-or-folder
//
// https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/file-system/how-to-write-to-a-text-file
//
// .NET Framework 4.7.2
//
// Specify a name for your top-level folder.
string folderName = @"C:\Users\david\Desktop\Book3";
// To create a string that specifies the path to a subfolder under your
// top-level folder, add a name for the subfolder to folderName.
string pathString = System.IO.Path.Combine(folderName, "_rels");
System.IO.Directory.CreateDirectory(pathString);
pathString = System.IO.Path.Combine(folderName, "docProps");
System.IO.Directory.CreateDirectory(pathString);
pathString = System.IO.Path.Combine(folderName, "xl");
System.IO.Directory.CreateDirectory(pathString);
string subPathString = System.IO.Path.Combine(pathString, "_rels");
System.IO.Directory.CreateDirectory(subPathString);
subPathString = System.IO.Path.Combine(pathString, "theme");
System.IO.Directory.CreateDirectory(subPathString);
subPathString = System.IO.Path.Combine(pathString, "worksheets");
System.IO.Directory.CreateDirectory(subPathString);
// Keep the console window open in debug mode.
System.Console.WriteLine("Press any key to exit.");
System.Console.ReadKey();
}
}
接下来，创建文本文件以保存描述Excel电子表格所需的XML。
namespace MakeFiles3
{
class Program
{
static void Main(string[] args)
{
//
// https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/file-system/how-to-write-to-a-text-file
//
// .NET Framework 4.7.2
//
string fileName = @"C:\Users\david\Desktop\Book3\_rels\.rels";
fnWriteFile(fileName);
fileName = @"C:\Users\david\Desktop\Book3\docProps\app.xml";
fnWriteFile(fileName);
fileName = @"C:\Users\david\Desktop\Book3\docProps\core.xml";
fnWriteFile(fileName);
fileName = @"C:\Users\david\Desktop\Book3\xl\_rels\workbook.xml.rels";
fnWriteFile(fileName);
fileName = @"C:\Users\david\Desktop\Book3\xl\theme\theme1.xml";
fnWriteFile(fileName);
fileName = @"C:\Users\david\Desktop\Book3\xl\worksheets\sheet1.xml";
fnWriteFile(fileName);
fileName = @"C:\Users\david\Desktop\Book3\xl\styles.xml";
fnWriteFile(fileName);
fileName = @"C:\Users\david\Desktop\Book3\xl\workbook.xml";
fnWriteFile(fileName);
fileName = @"C:\Users\david\Desktop\Book3\[Content_Types].xml";
fnWriteFile(fileName);
// Keep the console window open in debug mode.
System.Console.WriteLine("Press any key to exit.");
System.Console.ReadKey();
bool fnWriteFile(string strFilePath)
{
if (!System.IO.File.Exists(strFilePath))
{
using (System.IO.FileStream fs = System.IO.File.Create(strFilePath))
{
return true;
}
}
else
{
System.Console.WriteLine("File \"{0}\" already exists.", strFilePath);
return false;
}
}
}
}
}
接下来用XML填充文本文件。
所需的XML相当详细，因此您可能需要使用此github存储库。

using System.IO;

StartExstream(xContents, xFilename);

StartExstream(xContents, xFilename);
// Keep the console window open in debug mode.
System.Console.WriteLine("Press any key to exit.");
System.Console.ReadKey();
bool StartExstream(string strLine, string strFileName)
{
// Write the string to a file.
using (StreamWriter outputFile = new StreamWriter(strFileName))
{
outputFile.WriteLine(strLine);
return true;
}
}
}
}
}
最后对包含XML的文件夹结构进行ZIP-
namespace ZipFolder
// .NET Framework 4.7.2
// https://stackoverflow.com/questions/15241889/i-didnt-find-zipfile-class-in-the-system-io-compression-namespace?answertab=votes#tab-top
{
class Program
{
static void Main(string[] args)
{
string xlPath = @"C:\Users\david\Desktop\Book3.xlsx";
string folderPath = @"C:\Users\david\Desktop\Book3";
System.IO.Compression.ZipFile.CreateFromDirectory(folderPath, xlPath);
// Keep the console window open in debug mode.
System.Console.WriteLine("Press any key to exit.");
System.Console.ReadKey();
}
}
}
这将生成一个名为Book3.xlsx的Excel文件，该文件有效并在Windows 11上的Excel 365中干净地打开。
结果是一个非常简单的Excel电子表格，但您可能需要对更复杂的版本进行反向工程。以下是解压.xlsx文件的代码。
namespace UnZipXL
// .NET Framework 4.7.2
// https://stackoverflow.com/questions/15241889/i-didnt-find-zipfile-class-in-the-system-io-compression-namespace?answertab=votes#tab-top
{
class Program
{
static void Main(string[] args)
{
string XLPath = @"C:\Users\david\Desktop\Book2.xlsx";
string extractPath = @"C:\Users\david\Desktop\extract";
System.IO.Compression.ZipFile.ExtractToDirectory(XLPath, extractPath);
// Keep the console window open in debug mode.
System.Console.WriteLine("Press any key to exit.");
System.Console.ReadKey();
}
}
}
更新：
下面是更新Excel文件的代码片段。这又很简单。
//

// .NET Framework 4.7.2

using System.IO;

{
class Program
{
static void Main(string[] args)
{
string xContents = @"a";
string xFilename = @"a";
xFilename = @"C:\Users\david\Desktop\Book3\xl\worksheets\sheet1.xml";
xContents = @"<?xml version=""1.0"" encoding=""UTF-8"" standalone=""yes""?><worksheet xmlns=""http://schemas.openxmlformats.org/spreadsheetml/2006/main"" xmlns:r=""http://schemas.openxmlformats.org/officeDocument/2006/relationships"" xmlns:mc=""http://schemas.openxmlformats.org/markup-compatibility/2006"" mc:Ignorable=""x14ac xr xr2 xr3"" xmlns:x14ac=""http://schemas.microsoft.com/office/spreadsheetml/2009/9/ac"" xmlns:xr=""http://schemas.microsoft.com/office/spreadsheetml/2014/revision"" xmlns:xr2=""http://schemas.microsoft.com/office/spreadsheetml/2015/revision2"" xmlns:xr3=""http://schemas.microsoft.com/office/spreadsheetml/2016/revision3"" xr:uid=""{54E3D330-4E78-4755-89E0-1AADACAC4953}""><dimension ref=""A1:A3""/><sheetViews><sheetView tabSelected=""1"" workbookViewId=""0""><selection activeCell=""A4"" sqref=""A4""/></sheetView></sheetViews><sheetFormatPr defaultRowHeight=""15"" x14ac:dyDescent=""0.25""/><sheetData><row r=""1"" spans=""1:1"" x14ac:dyDescent=""0.25""><c r=""A1""><v>1</v></c></row><row r=""2"" spans=""1:1"" x14ac:dyDescent=""0.25""><c r=""A2""><v>2</v></c></row><row r=""3"" spans=""1:1"" x14ac:dyDescent=""0.25""><c r=""A3""><v>3</v></c></row></sheetData><pageMargins left=""0.7"" right=""0.7"" top=""0.75"" bottom=""0.75"" header=""0.3"" footer=""0.3""/></worksheet>";
xContents = xContents.Remove(941, 1).Insert(941, "0"); // character to replace is at 942 => index 941
StartExstream(xContents, xFilename);
// Keep the console window open in debug mode.
System.Console.WriteLine("Press any key to exit.");
System.Console.ReadKey();
bool StartExstream(string strLine, string strFileName)
{
// Write the string to a file.
using (StreamWriter outputFile = new StreamWriter(strFileName))
{
outputFile.WriteLine(strLine);
return true;
}
}
}
}
}
更新2-除了Mac上的文件夹路径外，此代码几乎没有变化。使用Microsoft Excel Online、.NET Framework 3.1、Visual Studio 2019 for Mac、MacOS Monterey 12.1。
我想知道为什么没有人建议PowerShell使用免费的ImportExcel模块；它可以轻松创建XML Excel文件（xlsx）。
从SQL Server等数据库创建Excel工作表时尤其容易。。。
IKVM+波伊
或者，你可以使用Interop。。。
