Question

我有两个插入语句，它们在数据库中插入记录。我使用了事务范围，以便在任何语句失败的情况下，没有任何记录得到更新。在第二个过程中，插入失败但它在第一个语句的数据库中插入记录。我在代码中缺少什么？

连接字符串

<add name="Transac.Properties.Settings.TransacDbConnectionString" connectionString="Data Source=.\sqlexpress;Initial Catalog=Transac;Integrated Security=True" providerName="System.Data.SqlClient" />

private void button1_Click(object sender, EventArgs e) {
    var scopeOptions = new TransactionOptions();
    scopeOptions.IsolationLevel = System.Transactions.IsolationLevel.ReadCommitted;
    scopeOptions.Timeout = TimeSpan.MaxValue;

    using (TransactionScope transactionScope = new TransactionScope(TransactionScopeOption.Required,scopeOptions)) {
        try {

                cmd = new SqlCommand("SalesSave", con);
                cmd.CommandType = CommandType.StoredProcedure;

                cmd.Parameters.Add(new SqlParameter("@BillNo", lblBillNo.Text));
                cmd.Parameters.Add(new SqlParameter("@CustName", cboCust_Name.Text.ToUpper()));
                cmd.Parameters.Add(new SqlParameter("@Mobile", txtMob.Text));
                cmd.ExecuteNonQuery();


                cmd = new SqlCommand("SubSave", con);
                cmd.CommandType = CommandType.StoredProcedure;
                cmd.Parameters.Add(new SqlParameter("@SubBillNo", lblBillNo.Text));
                cmd.Parameters.Add(new SqlParameter("@ItemName", dataGridView1.Rows[i].Cells[0].Value.ToString().ToUpper()));
                cmd.Parameters.Add(new SqlParameter("@Qty", dataGridView1.Rows[i].Cells[1].Value.ToString()));
                //cmd.Parameters.Add(new SqlParameter("@Price", dataGridView1.Rows[i].Cells[2].Value.ToString()));
                cmd.ExecuteNonQuery();

            transactionScope.Complete();
            transactionScope.Dispose();
        }
        catch (Exception e1) {
            MessageBox.Show(e1.Message);
        }
    }
}

存储过程1：

ALTER PROCEDURE [dbo].[SalesSave]
(  
    @SalesBillNo as varchar(50),
    @CustName as varchar(50),
    @Mobile as nvarchar(50)

)   
AS
    begin
        insert into Sales(

                         SalesBillno,
                         CustName,
                         Mobile

                         )

                values (

                         @SalesBillNo,
                         @CustName,
                         @Mobile

                         )
    end

存储过程2

ALTER PROCEDURE [dbo].[SubSave]
@SubSalesBillNo as varchar(50),
@ItemName as nvarchar(50),
@Qty as money,
@Price as money

AS
    begin
         INSERT INTO SubSales 
         VALUES(
                @SubSalesBillNo,
                @ItemName,
                @Qty,
                @Price   
                )
    end

我相信您必须在事务范围内打开数据库连接并使用它来实现此目的。
