在应用程序里嵌入资源，可以避免用户因删除资源文件而造成应用程序出现错误。要使用资源文件中的文件，只需要按下面的方法调用即可：
VB.net
<![CDATA[Function GetEmbeddedResource(ByVal strname As String) As System.IO.Stream
Return System.Reflection.Assembly.GetExecutingAssembly.GetManifestResourceStream(strname)
End Function
]]>C#
<![CDATA[System.IO.Stream GetEmbeddedResource(string strname){
return System.Reflection.Assembly.GetExecutingAssembly.GetManifestResourceStream(strname) ;
}
]]>
其中的参数strname必须是下面的格式：..，比如： "MyApplication.Icon1.ico"。参数是大小写敏感的。如果不正确或者缺少文件，将会出现返回Null的错误。
要在你的引用程序中嵌入文件，只需要按下面的步骤操作即可：
1，在资源管理器里选中文件
2，按住鼠标左键，拖到工程文件上，松开鼠标左键。
3，在拖放的文件上点鼠标右键，选“属性”
4，在生成操作里选择“嵌入的资源”。
在进行测试之前，请准备好以下几个文件：1.ico,2.ico,Text.rtf,xsl.txt,rose.jpg?http://www.xvna.com,Test.jpg?http://www.xvna.com，结果如下：
下面是完整的例子：
