备份一个有的时候，可能需要把其它exe或者dll包含在主程序中....

1、选中附件，右键生成操作选择 嵌入的资源，例如：handle.exe

2、FileUtil

 1 using System.IO;
 2 using System.Reflection;
 3 
 4 namespace ResourceOccupancyHelp
 5 {
 6     public class FileUtil
 7     {
 8         /// <summary>
 9         /// 从资源文件中抽取资源文件
10         /// </summary>
11         /// <param name="resFileName">资源文件名称（资源文件名称必须包含目录，目录间用“.”隔开,最外层是项目默认命名空间）</param>
12         /// <param name="outputFile">输出文件</param>
13         public static void ExtractResFile(string resFileName, string outputFile)
14         {
15             BufferedStream inStream = null;
16             FileStream outStream = null;
17             try
18             {
19                 Assembly asm = Assembly.GetExecutingAssembly(); //读取嵌入式资源
20                 inStream = new BufferedStream(asm.GetManifestResourceStream(resFileName));
21                 outStream = new FileStream(outputFile, FileMode.Create, FileAccess.Write);
22 
23                 byte[] buffer = new byte[1024];
24                 int length;
25 
26                 while ((length = inStream.Read(buffer, 0, buffer.Length)) > 0)
27                 {
28                     outStream.Write(buffer, 0, length);
29                 }
30                 outStream.Flush();
31             }
32             finally
33             {
34                 if (outStream != null)
35                 {
36                     outStream.Close();
37                 }
38                 if (inStream != null)
39                 {
40                     inStream.Close();
41                 }
42             }
43         }
44     }
45 }

3、调用demo

FileUtil.ExtractResFile("ResourceOccupancyHelp.handle.exe", System.IO.Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "handle.exe"));

特别注意，生成的exe需要用命名空间最前缀，如果有文件夹的话也需要完整加上。
