推荐答案

非常明显。



您正在通过 CustomerID



cmd.Parameters.Add（@ CustomerID，SqlDbType.Int，20）.Value = CustomerID;



存储时程序有拼写错误并且需要 CustomeID

Pretty obvious.

You are passing CustomerID

cmd.Parameters.Add("@CustomerID", SqlDbType.Int, 20).Value = CustomerID;

while stored procedure has a typo and expects CustomeID

ALTER PROCEDURE [dbo].[SearchCustomer]
@CustomeID int
AS

建议：注意拼写检查提示。
