从字符串“select custName from tblCustMst”到“Integer”类型的转换无效

Question

下面的代码在第二个声明中给出了转换异常。

 Dim query As String = "select CustName from tblCustMst " & "where PlantId=@PlantId"
 cmd.CommandType = query

Answer 1

您应该使用cmd.CommandText 试试这个：

Dim query As String = "select CustName from tblCustMst " & "where PlantId=@PlantId"
cmd.CommandText= query

祝你好运。
