Spreadsheet引用异常解决

当出现已下异常时： 

“this.axSpreadsheet1.DataSource = null;”

Error 1 The type 'msdatasrc.DataSource' is defined in an assembly that is not referenced. You must add a reference to assembly 'MSDATASRC, Version=7.0.3300.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. 

解决办法：

1.找到目录：C:\Windows\assembly\GAC\MSDATASRC\7.0.3300.0__b03f5f7f11d50a3a

2.引用 MSDATASRC.dll

 

然后就是：Build succeeded !
