选择数据表行,按guid筛选

你可以尝试这样的方法:

C:

var filteredRows = from dtr in yourDataTable.Rows
                   where ((System.Guid)dtr["MyGuidColumn"]) == myFilterGuid
                   select dtr;

VB:

Dim filteredRows = From dtr In yourDataTable.Rows _
                   Where DirectCast(dtr("MyGuidColumn"), System.Guid) = myFilterGuid _
                   Select dtr
