如何使用StreamReader读取嵌入式资源(文本文件)并将其作为字符串返回?我当前的脚本使用Windows窗体和文本框,允许用户查找和替换未嵌入的文本文件中的文本。

private void button1_Click(object sender, EventArgs e)
{
    StringCollection strValuesToSearch = new StringCollection();
    strValuesToSearch.Add("Apple");
    string stringToReplace;
    stringToReplace = textBox1.Text;

    StreamReader FileReader = new StreamReader(@"C:\MyFile.txt");
    string FileContents;
    FileContents = FileReader.ReadToEnd();
    FileReader.Close();
    foreach (string s in strValuesToSearch)
    {
        if (FileContents.Contains(s))
            FileContents = FileContents.Replace(s, stringToReplace);
    }
    StreamWriter FileWriter = new StreamWriter(@"MyFile.txt");
    FileWriter.Write(FileContents);
    FileWriter.Close();
}

我读取了一个嵌入式资源文本文件,使用:

    /// <summary>
    /// Converts to generic list a byte array
    /// </summary>
    /// <param name="content">byte array (embedded resource)</param>
    /// <returns>generic list of strings</returns>
    private List<string> GetLines(byte[] content)
    {
        string s = Encoding.Default.GetString(content, 0, content.Length - 1);
        return new List<string>(s.Split(new[] { Environment.NewLine }, StringSplitOptions.None));
    }

示例:

var template = GetLines(Properties.Resources.LasTemplate /* resource name */);

template.ForEach(ln =>
{
    Debug.WriteLine(ln);
});

其他回答

我知道这是一条古老的线索,但这对我来说是有效的:

将文本文件添加到项目资源将访问修饰符设置为public,如Andrew Hill所示阅读文本如下:textBox1=新文本框();textBox1.Text=属性.Resources.SomeText;

我添加到资源中的文本:“SomeText.txt”

读取表单加载事件上的嵌入式TXT文件。

动态设置变量。

string f1 = "AppName.File1.Ext";
string f2 = "AppName.File2.Ext";
string f3 = "AppName.File3.Ext";

呼叫Try Catch。

try 
{
     IncludeText(f1,f2,f3); 
     /// Pass the Resources Dynamically 
     /// through the call stack.
}

catch (Exception Ex)
{
     MessageBox.Show(Ex.Message);  
     /// Error for if the Stream is Null.
}

为IncludeText()创建Void,Visual Studio将为您完成此操作。单击灯泡以自动生成代码块。

将以下内容放入生成的代码块中

资源1

var assembly = Assembly.GetExecutingAssembly();
using (Stream stream = assembly.GetManifestResourceStream(file1))
using (StreamReader reader = new StreamReader(stream))
{
string result1 = reader.ReadToEnd();
richTextBox1.AppendText(result1 + Environment.NewLine + Environment.NewLine );
}

资源2

var assembly = Assembly.GetExecutingAssembly();
using (Stream stream = assembly.GetManifestResourceStream(file2))
using (StreamReader reader = new StreamReader(stream))
{
string result2 = reader.ReadToEnd();
richTextBox1.AppendText(
result2 + Environment.NewLine + 
Environment.NewLine );
}

资源3

var assembly = Assembly.GetExecutingAssembly();
using (Stream stream = assembly.GetManifestResourceStream(file3))

using (StreamReader reader = new StreamReader(stream))
{
    string result3 = reader.ReadToEnd();
    richTextBox1.AppendText(result3);
}

如果您希望将返回的变量发送到其他地方,只需调用另一个函数并。。。

using (StreamReader reader = new StreamReader(stream))
{
    string result3 = reader.ReadToEnd();
    ///richTextBox1.AppendText(result3);
    string extVar = result3;

    /// another try catch here.

   try {

   SendVariableToLocation(extVar)
   {
         //// Put Code Here.
   }

       }

  catch (Exception ex)
  {
    Messagebox.Show(ex.Message);
  }

}

这是一种将多个txt文件合并并在单个富文本框中读取其嵌入数据的方法。这是我期望的代码示例的效果。

public class AssemblyTextFileReader
{
    private readonly Assembly _assembly;

    public AssemblyTextFileReader(Assembly assembly)
    {
        _assembly = assembly ?? throw new ArgumentNullException(nameof(assembly));
    }

    public async Task<string> ReadFileAsync(string fileName)
    {
        var resourceName = _assembly.GetManifestResourceName(fileName);

        using (var stream = _assembly.GetManifestResourceStream(resourceName))
        {
            using (var reader = new StreamReader(stream))
            {
                return await reader.ReadToEndAsync();
            }
        }
    }
}

public static class AssemblyExtensions
{
    public static string GetManifestResourceName(this Assembly assembly, string fileName)
    {
        string name = assembly.GetManifestResourceNames().SingleOrDefault(n => n.EndsWith(fileName, StringComparison.InvariantCultureIgnoreCase));

        if (string.IsNullOrEmpty(name))
        {
            throw new FileNotFoundException($"Embedded file '{fileName}' could not be found in assembly '{assembly.FullName}'.", fileName);
        }

        return name;
    }
}
// To use the code above:
var reader = new AssemblyTextFileReader(assembly);

string text = await reader.ReadFileAsync(@"MyFile.txt");

我很恼火,你必须在字符串中始终包含名称空间和文件夹。我想简化对嵌入式资源的访问。这就是我写这个小课堂的原因。欢迎使用和改进!

用法:

using(Stream stream = EmbeddedResources.ExecutingResources.GetStream("filename.txt"))
{
 //...
}

类别:

public class EmbeddedResources
{
    private static readonly Lazy<EmbeddedResources> _callingResources = new Lazy<EmbeddedResources>(() => new EmbeddedResources(Assembly.GetCallingAssembly()));

    private static readonly Lazy<EmbeddedResources> _entryResources = new Lazy<EmbeddedResources>(() => new EmbeddedResources(Assembly.GetEntryAssembly()));

    private static readonly Lazy<EmbeddedResources> _executingResources = new Lazy<EmbeddedResources>(() => new EmbeddedResources(Assembly.GetExecutingAssembly()));

    private readonly Assembly _assembly;

    private readonly string[] _resources;

    public EmbeddedResources(Assembly assembly)
    {
        _assembly = assembly;
        _resources = assembly.GetManifestResourceNames();
    }

    public static EmbeddedResources CallingResources => _callingResources.Value;

    public static EmbeddedResources EntryResources => _entryResources.Value;

    public static EmbeddedResources ExecutingResources => _executingResources.Value;

    public Stream GetStream(string resName) => _assembly.GetManifestResourceStream(_resources.Single(s => s.Contains(resName)));

}

我读取了一个嵌入式资源文本文件,使用:

    /// <summary>
    /// Converts to generic list a byte array
    /// </summary>
    /// <param name="content">byte array (embedded resource)</param>
    /// <returns>generic list of strings</returns>
    private List<string> GetLines(byte[] content)
    {
        string s = Encoding.Default.GetString(content, 0, content.Length - 1);
        return new List<string>(s.Split(new[] { Environment.NewLine }, StringSplitOptions.None));
    }

示例:

var template = GetLines(Properties.Resources.LasTemplate /* resource name */);

template.ForEach(ln =>
{
    Debug.WriteLine(ln);
});
