C# 模拟器“多连接" [英] C# Emulator 'To Many Connections'

问题描述

我最近收到一个 mysql to many connectioniions 错误，我使用了 sql 查询，例如下面的一个

I have recently been receiving a mysql to many connectiions error, ive used sql queries such as the one below

SET GLOBAL max_conmnections = 8000; 并且我还将 mysql.pool.max 提高到 8000 并且当我的模拟器在调试器中时，它会在此空白处崩溃

SET GLOBAL max_conmnections = 8000; and ive also higherd the mysql.pool.max to 8000 and when my emulator is in the debugger, it crashes on this void

private static SqlDatabaseClient CreateClient(int Id)
{
     MySqlConnection Connection = new MySqlConnection(GenerateConnectionString());
     Connection.Open();

     return new SqlDatabaseClient(Id, Connection);
}

突出显示导致它崩溃的行是 connection.open(); 它发生在我收到 10-12 个在线连接时，模拟器在调试器中运行了 7-8 小时！

the line thats highlighted that has caused it to crash was connection.open(); it happens when i receive 10-12 online connections, the emulator was running for 7-8 hours in the debugger!

推荐答案

你可以尝试的是关闭并配置 C# 使用后的连接和命令 使用声明:

What you can try is to close and dispose the connection and commands after used by the C# using statement:

private static SqlDatabaseClient CreateClient(int Id)
{
    Int32 returnId = 0;

    try
    {
      using(MySqlConnection connection = new MySqlConnection(GenerateConnectionString()))
      {
        connection.Open();

        if(connection.State == ConnectionState.Open)
        {
           returnId = Id;
        }

      }
    }
    catch(Exception exception)
    {
       Console.Write(ex.Message);
    }
    finally
    {
        if(connection.State == ConnectionState.Open)
        {
           connection.Close();

        }
    }

    return returnId;
}
