使用ILDASM.EXE工具！
写了两个小程序进行测试，一个使用C#语言，另外一个使用VB.NET语言。
d:\Mesh\study\VBAppDetect>dir /b
CSharpApp.exe
VBApp.exe
d:\Mesh\study\VBAppDetect>ildasm /tok /byt CSharpApp.exe /out=CSharpApp_manifest
.txt
d:\Mesh\study\VBAppDetect>type CSharpApp_manifest.txt | find /i "Microsoft.Visua
lBasic"
啥都没有，呵呵
d:\Mesh\study\VBAppDetect>ildasm /tok /byt VBApp.exe /out=VBApp_manifest.txt
d:\Mesh\study\VBAppDetect>type VBApp_manifest.txt | find /i "Microsoft.VisualBas
ic"
一大堆引用Microsoft.VisualBasic的方法、属性等，说明使用了VB.NET里面的东西了。
