在C#中,使用SqlDataAdapter进行事务管理需要遵循以下步骤:
SqlConnection connection = new SqlConnection("your_connection_string");
connection.Open();
SqlCommand command = new SqlCommand("your_sql_statement", connection);
SqlTransaction transaction = connection.BeginTransaction();
command.Transaction = transaction;
SqlDataAdapter adapter = new SqlDataAdapter();
adapter.SelectCommand = command;
DataTable dataTable = new DataTable();
adapter.Fill(dataTable);
transaction.Commit();
try
{
// 执行数据库操作
transaction.Commit();
}
catch (Exception ex)
{
// 发生错误时回滚事务
transaction.Rollback();
throw ex;
}
finally
{
// 关闭连接
connection.Close();
}
将以上代码整合在一起,可以创建一个使用SqlDataAdapter进行事务管理的示例:
using System;
using System.Data;
using System.Data.SqlClient;
class Program
{
static void Main()
{
string connectionString = "your_connection_string";
string sqlStatement = "your_sql_statement";
using (SqlConnection connection = new SqlConnection(connectionString))
{
connection.Open();
using (SqlCommand command = new SqlCommand(sqlStatement, connection))
{
SqlTransaction transaction = connection.BeginTransaction();
command.Transaction = transaction;
using (SqlDataAdapter adapter = new SqlDataAdapter())
{
adapter.SelectCommand = command;
DataTable dataTable = new DataTable();
adapter.Fill(dataTable);
try
{
transaction.Commit();
}
catch (Exception ex)
{
transaction.Rollback();
throw ex;
}
}
}
}
}
}
请注意替换your_connection_string
和your_sql_statement
为实际的连接字符串和SQL语句。
