从标签文本字段获取数据的问题

Question

Following code I am using in rating system. 以下代码我在评分系统中使用。 I am able to print text from script to label but I am not able to store it in the database. 我可以将文本从脚本打印到标签，但无法将其存储在数据库中。 If I store it in database, it is showing zero only for the id=@a1 but all other values are getting stored into database. 如果我将其存储在数据库中，则它仅对id=@a1显示为零，但所有其他值都将存储到数据库中。

stored procedure 存储过程

    CREATE PROCEDURE RatingStorage1
            @DID int,
            @EMPID int,
            @SNL int,
            @SNB int,
            @A1 int,
     AS
     BEGIN
            insert into RatingStorage values (@DID,@EMPID,@SNL,@SNB,@A1)
      END

Answer 1

A1.Text has the string value but you have take @A1 parameter as Int in your stored procedure. A1.Text具有字符串值，但是您在存储过程中将@A1参数作为Int 。 So you have to convert it into Integer like this: 因此，您必须像这样将其转换为Integer ：

 cmd.Parameters.AddWithValue("@A1",Convert.ToInt32(A1.Text))

我使用了隐藏字段而不是标签，我可以将其存储到数据库中
