How to use transactionscope

How to use transactionscope: 1. Introduce a namespace; 2. Create a TransactionScope object; 3. Start a transaction; 4. Perform database operations; 5. Submit or rollback the transaction. Detailed introduction: 1. Introduce the namespace. Before using TransactionScope, you need to introduce the System.Transactions namespace; 2. Create a TransactionScope object, when using TransactionScope, etc.

TransactionScope is a transaction management class provided in the .NET framework, which can help developers better manage database transactions in code. The following is how to use TransactionScope:

1. Introduce the namespace

Before using TransactionScope, you need to introduce the System.Transactions namespace.

using System.Transactions;

2. Create a TransactionScope object

When using TransactionScope, you need to create a TransactionScope object. When creating an object, you can specify its behavior, such as timeout, isolation level, etc.

using (TransactionScope scope = new TransactionScope())  
{  
    // 在这里执行数据库操作  
}

3. Start a transaction

After the TransactionScope object is created, you need to call its BeginTransaction method to start a new transaction.

scope.BeginTransaction();

4. Perform database operations

Perform database operations within a transaction. These operations can be inserting, updating or deleting data, etc. If all operations execute successfully, the transaction can be committed; if any one operation fails, the transaction can be rolled back.

// 执行数据库操作  
// ...

5. Submit or rollback the transaction

After the transaction ends, you need to call the Commit method of the TransactionScope object to commit the transaction. If an error occurs during transaction execution, you can call the Rollback method to roll back the transaction.

try  
{  
    // 提交事务  
    scope.Commit();  
}  
catch (Exception ex)  
{  
    // 回滚事务  
    scope.Rollback();  
    // 处理异常  
}

It should be noted that the TransactionScope object needs to be released after use to release resources. This is achieved by using the using statement. When the using statement block is executed, the Dispose method of the TransactionScope object will be automatically called to release the resources. At the same time, if the transaction within the TransactionScope object needs to be rolled back, the transaction will be automatically rolled back at the end of the using statement block. Therefore, when using TransactionScope, it is recommended to always use using statements to manage it.
