使用存儲過程操作數據，使用c處理數據＃

Question

我有3個存儲過程在3個不同的表上，其主要目的是插入，刪除，查看和更新​​。

我有一個註冊表單，其中包含9個字段，需要由用戶填寫。一旦用戶點擊提交，前3個字段數據將被髮送到第一SP，接下來的3到第二個SP，以及最後3到第三個SP。

我正在尋找執行事務來做到這一點..這樣，如果所有的數據成功添加，它的提交或否則整個數據應該回滾。

string connectionString = 
WebConfigurationManager.ConnectionStrings["Northwind"].ConnectionString; 
SqlConnection con = new SqlConnection(connectionString); 
SqlCommand cmd1 = new SqlCommand(con, CommandType.StoredProcedure, "usp_additemdata",  p); 
SqlCommand cmd2 = new SqlCommand(con, CommandType.StoredProcedure, "usp_addpricedata", p) 
SqlTransaction tran = null; 
try 
{ 

con.Open(); 

cmd1.Transaction = tran; 
cmd2.Transaction = tran; 

cmd1.ExecuteNonQuery(); 
cmd2.ExecuteNonQuery(); 
Commit the transaction. 
tran.Commit(); 
} 
catch 
{ 

tran.Rollback(); 
} 
finally 
{ 
con.Close(); 
} 

Answer 1

您可以使用Transaction Scope這裏

using (TransactionScope scope = new TransactionScope()) 
    { 
     using (SqlConnection connection1 = new SqlConnection(yourconnectionstring)) 
     { 
      //your commands here 
     } 

     // The Complete method commits the transaction. If an exception has been thrown, 
     // Complete is not called and the transaction is rolled back. 
     scope.Complete(); 
    } 

Answer 2

SqlConnection db = new SqlConnection("ConnectionStringHere"); 
     SqlTransaction transaction; 

    db.Open(); 
    transaction = db.BeginTransaction(); 
    try 
    { 
    var SqlC1= new SqlCommand("SP1", db, transaction); 
    <Add parameters in SqlC1> 
     SqlC1.ExecuteNonQuery(); 
    var SqlC2= new SqlCommand("SP2", db, transaction); 
    <Add parameters in SqlC2> 
     SqlC2.ExecuteNonQuery(); 

    var SqlC3= new SqlCommand("SP3", db, transaction); 
    <Add parameters in SqlC3> 
     SqlC3.ExecuteNonQuery(); 
    transaction.Commit(); 
    } 
    catch (SqlException sqlError) 
    { 
    transaction.Rollback(); 
    } 
    db.Close();**strong text**
