C# 过程或函数“insertcustrec5”需要未提供的参数“@tb1”

当我单击页面中的Save按钮时，它会执行此操作

protected void btnsave_Click(object sender, EventArgs e)

然后调用save函数。 在save函数中，它调用存储过程insertcustrec5。一旦到达存储过程insertcustrec5，就会引发错误

过程或函数“insertcustrec5”需要参数“@tb1”， 这是没有提供的

但是我提供了..n我检查了每个参数，得到了它的值，但这个错误仍然不断发生

->我的存储过程是：

ALTER procedure [dbo].[insertcustrec5]
 (
   @RID int,
   @Remarks varchar(MAX),
   @CRDate date,
   @ChallanNo float,
   @Quantity float,
   @tb1 int,
   @Amount float
 )
 As
 INSERT INTO Customer_Receive(ChallanNo, CRDate, RID, Quantity, Remarks,CustID,Amount)
 VALUES     (@ChallanNo,@CRDate,@RID,@Quantity,@Remarks,@tb1,@Amount)

public void save()
    {

        data.AddParameter("RID", this.rid);
        data.AddParameter("CustID", this.tb1);
        data.AddParameter("Remarks", this.remarks);
        data.AddParameter("CRDate", this.CRDate);
        data.AddParameter("ChallanNo", this.ChallanNo);
        data.AddParameter("Quantity", this.quantity);
        data.ExecuteNonQuery("insertcustrec5");

->调用存储过程的Save函数是：

ALTER procedure [dbo].[insertcustrec5]
 (
   @RID int,
   @Remarks varchar(MAX),
   @CRDate date,
   @ChallanNo float,
   @Quantity float,
   @tb1 int,
   @Amount float
 )
 As
 INSERT INTO Customer_Receive(ChallanNo, CRDate, RID, Quantity, Remarks,CustID,Amount)
 VALUES     (@ChallanNo,@CRDate,@RID,@Quantity,@Remarks,@tb1,@Amount)

public void save()
    {

        data.AddParameter("RID", this.rid);
        data.AddParameter("CustID", this.tb1);
        data.AddParameter("Remarks", this.remarks);
        data.AddParameter("CRDate", this.CRDate);
        data.AddParameter("ChallanNo", this.ChallanNo);
        data.AddParameter("Quantity", this.quantity);
        data.ExecuteNonQuery("insertcustrec5");

->执行查询功能：-

public int ExecuteNonQuery(string commandText)
    {
        try
        {
            SqlCommand command = new SqlCommand(commandText);
            command.CommandType = System.Data.CommandType.StoredProcedure;
            this.OpenConnection();
            command.Connection = this.connection;
            command.Parameters.AddRange(cmdParams.ToArray());
            return command.ExecuteNonQuery();
        }
        finally
        {
            this.CloseConnection();
        }
    }

->保存按钮单击：-

 protected void btnsave_Click(object sender, EventArgs e)
    {
        bllCustomer_Receive receive = new bllCustomer_Receive();
        string datetime = txtcrdate.Text;
        DateTime dt = DateTime.ParseExact(datetime, "d/M/yyyy", null);
        receive.CRDate = dt;
        receive.ChallanNo = txtchallan.Text;
        receive.rid = txtrid.Text;
        receive.quantity = float.Parse(txtquantity.Text);
        receive.remarks = txtremarks.Text;
        tb1.Text = Convert.ToString(drpdwncustID.SelectedItem);
        receive.tb1 = tb1.Text;
        receive.save();
    }

好的，您没有提供@tb1参数，正如代码的以下部分中所述的错误：

    data.AddParameter("RID", this.rid);
    data.AddParameter("CustID", this.tb1);
    data.AddParameter("Remarks", this.remarks);
    data.AddParameter("CRDate", this.CRDate);
    data.AddParameter("ChallanNo", this.ChallanNo);
    data.AddParameter("Quantity", this.quantity);
    data.ExecuteNonQuery("insertcustrec5");

---

同时，您还应该添加一行来添加@amount参数…

在向sp添加参数时写入

data.AddParameter("tb1", this.tb1);

而不是

 data.AddParameter("CustID", this.tb1);

你没有提供。你有没有读过你发布的代码？注意：当你为tb1修复这个问题时，你会在数量上遇到类似的问题…但是我提供了..n我检查了每个参数，得到了它的值，但这个错误仍然不断发生。事实并非如此。您没有提供参数或没有向我们显示真实代码。
