创建一个新的随机密钥对:sn -k myTest.snk
第一步： 将DLL文件解开 ildasm myTest.dll /out:myTest.il
第二步： 将签名合入DLL ilasm myTest.il /res:myTest.res /dll /key:myTest.snk /out:myTestSN.dll
第三步： 检查 sn -vf myTestSN.dll
例如：
C:/Program Files/Microsoft Visual Studio 8/SDK/v2.0>ildasm C:/Salien.Utility.V2005.dll /out:C:/Salien.Utility.V2005.il
C:/Program Files/Microsoft Visual Studio 8/SDK/v2.0>ildasm C:/Salien.Utility.V2005.dll /out:C:/Salien.Utility.V2005.il
C:/Program Files/Microsoft Visual Studio 8/SDK/v2.0>ilasm C:/Salien.Utility.V2005.il /res:C:/Salien.Utility.V2005.res /dll /key:C:/Salien.Utility.V2005.snk /out:C:/Salien.Utility.V2005.dll
