问题描述

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 表单和文本框，允许用户在未嵌入的文本文件中查找和替换文本.

How do I read an embedded resource (text file) using StreamReader and return it as a string? My current script uses a Windows form and textbox that allows the user to find and replace text in a text file that is not embedded.

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();
}

推荐答案

您可以使用 Assembly.GetManifestResourceStream 方法:

添加以下用法

Add the following usings

using System.IO;
using System.Reflection;

设置相关文件的属性:
参数Build Action，值为Embedded Resource

使用以下代码

var assembly = Assembly.GetExecutingAssembly();
var resourceName = "MyCompany.MyProduct.MyFile.txt";

using (Stream stream = assembly.GetManifestResourceStream(resourceName))
using (StreamReader reader = new StreamReader(stream))
{
    string result = reader.ReadToEnd();
}

resourceName 是嵌入在 assembly 中的资源之一的名称.例如，如果您嵌入了一个名为 "MyFile.txt" 的文本文件，该文件位于具有默认命名空间 "MyCompany.MyProduct" 的项目的根目录中，则 >resourceName 是 "MyCompany.MyProduct.MyFile.txt".您可以使用获取程序集中所有资源的列表Assembly.GetManifestResourceNames 方法.

resourceName is the name of one of the resources embedded in assembly. For example, if you embed a text file named "MyFile.txt" that is placed in the root of a project with default namespace "MyCompany.MyProduct", then resourceName is "MyCompany.MyProduct.MyFile.txt". You can get a list of all resources in an assembly using the Assembly.GetManifestResourceNames Method.

仅从文件名中获取 resourceName 的明智之举(通过命名空间的东西):

A no brainer astute to get the resourceName from the file name only (by pass the namespace stuff):

string resourceName = assembly.GetManifestResourceNames()
  .Single(str => str.EndsWith("YourFileName.txt"));

一个完整的例子:

A complete example:

public string ReadResource(string name)
{
    // Determine path
    var assembly = Assembly.GetExecutingAssembly();
    string resourcePath = name;
    // Format: "{Namespace}.{Folder}.{filename}.{Extension}"
    if (!name.StartsWith(nameof(SignificantDrawerCompiler)))
    {
        resourcePath = assembly.GetManifestResourceNames()
            .Single(str => str.EndsWith(name));
    }

    using (Stream stream = assembly.GetManifestResourceStream(resourcePath))
    using (StreamReader reader = new StreamReader(stream))
    {
        return reader.ReadToEnd();
    }
}
