如何读取嵌入式资源文本文件

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();
}

当前回答

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

当您将文件添加到资源中时，您应该将其“访问修改器”选择为“公共”，然后再进行如下操作。

byte[] clistAsByteArray = Properties.Resources.CLIST01;

CLIST01是嵌入文件的名称。

实际上，您可以访问resources.Designer.cs，查看getter的名称。

这是一个类，您可能会发现从当前程序集读取嵌入式资源文件非常方便：

using System.IO;
using System.Linq;
using System.Text;
using System.Reflection;

public static class EmbeddedResourceUtils
{
    public static string ReadFromResourceFile(string endingFileName)
    {
        var assembly = Assembly.GetExecutingAssembly();
        var manifestResourceNames = assembly.GetManifestResourceNames();

        foreach (var resourceName in manifestResourceNames)
        {
            var fileNameFromResourceName = _GetFileNameFromResourceName(resourceName);
            if (!fileNameFromResourceName.EndsWith(endingFileName))
            {
                continue;
            }

            using (var manifestResourceStream = assembly.GetManifestResourceStream(resourceName))
            {
                if (manifestResourceStream == null)
                {
                    continue;
                }

                using (var streamReader = new StreamReader(manifestResourceStream))
                {
                    return streamReader.ReadToEnd();
                }
            }
        }

        return null;
    }
    
    // https://stackoverflow.com/a/32176198/3764804
    private static string _GetFileNameFromResourceName(string resourceName)
    {
        var stringBuilder = new StringBuilder();
        var escapeDot = false;
        var haveExtension = false;

        for (var resourceNameIndex = resourceName.Length - 1;
            resourceNameIndex >= 0;
            resourceNameIndex--)
        {
            if (resourceName[resourceNameIndex] == '_')
            {
                escapeDot = true;
                continue;
            }

            if (resourceName[resourceNameIndex] == '.')
            {
                if (!escapeDot)
                {
                    if (haveExtension)
                    {
                        stringBuilder.Append('\\');
                        continue;
                    }

                    haveExtension = true;
                }
            }
            else
            {
                escapeDot = false;
            }

            stringBuilder.Append(resourceName[resourceNameIndex]);
        }

        var fileName = Path.GetDirectoryName(stringBuilder.ToString());
        return fileName == null ? null : new string(fileName.Reverse().ToArray());
    }
}

如SonarCloud所示，更好的做法是：

public class Example
{
    public static void Main()
    { 
        // Compliant: type of the current class
        Assembly assembly = typeof(Example).Assembly; 
        Console.WriteLine("Assembly name: {0}", assem.FullName);

        // Non-compliant
        Assembly assembly = Assembly.GetExecutingAssembly();
        Console.WriteLine("Assembly name: {0}", assem.FullName);
    }
}

您也可以使用@dtb答案的简化版本：

public string GetEmbeddedResource(string ns, string res)
{
    using (var reader = new StreamReader(Assembly.GetExecutingAssembly().GetManifestResourceStream(string.Format("{0}.{1}", ns, res))))
    {
        return reader.ReadToEnd();
    }
}

在Visual Studio中，您可以通过项目财产（本例中为“分析”）的资源选项卡直接嵌入对文件资源的访问。

然后，可以通过

byte[] jsonSecrets = GoogleAnalyticsExtractor.Properties.Resources.client_secrets_reporter;

如果你需要它作为一个流，那么（从https://stackoverflow.com/a/4736185/432976 )

Stream stream = new MemoryStream(jsonSecrets)
