如何得到资源文件中的文件

作者:孟宪会    文章来源:网络    更新时间:2007-6-4 23:53:32

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 Function GetEmbeddedResource(ByVal strname As String) As System.IO.Stream Return System.Reflection.Assembly.GetExecutingAssembly.GetManifestResourceStream(strname) End Function C# 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,Test.jpg,结果如下:

下面是完整的例子:

' 模块文件 Module Module1 'VB.NET Function GetEmbeddedResource(ByVal strname As String) As System.IO.Stream Return System.Reflection.Assembly.GetExecutingAssembly.GetManifestResourceStream(strname) End Function 'C# 'System.IO.Stream GetEmbeddedResource(string strname) { 'return System.Reflection.Assembly.GetExecutingAssembly.GetManifestResourceStream(strname) ; '} End Module ' 主文件 Public Class Form1
