比较数据行中的值 VB
comparing values in a datarow VB
我想比较两个数据行 row 和 row1 中的值。但是此代码正在生成错误
For Each row As DataRow In dt.Rows
For Each row1 As DataRow In tmpdt.Rows
If row["STATE"].Tostring() = row1["STATE"].Tostring() Then
End If
Next
Next
错误:
Value of type 'System.Data.DataRow' cannot be converted to 'Boolean'
使用圆括号 ()
代替 []
这可行:
For Each row As DataRow In dt.Rows
For Each row1 As DataRow In tmpdt.Rows
If row("STATE").Tostring() = row1("STATE").Tostring() Then
End If
Next
Next
