我认为'sqlstring'你提到的是命令文本，请参考下面的链接

I think 'sqlstring' u mentioned is the command text refer the link below

Everything should be clear from this MSDN article: http://msdn.microsoft.com/en-us/library/system.data.sqltypes.sqlstring%28v=vs.110%29.aspx[^].

If this is not clear to you, you probably need to explain what concerns you — please see my comment to the question.
