C#MySql Connector /网络问题

作者:互联网

当前正在运行Mono.我在位于/usr/lib / mono / gac的gac文件夹中加载了MySQL并安装了connector / net.问题是每次我尝试使用简单的连接测试来运行它时,都会出现以下错误:

** (/home/holland/Code/csharp/test/Test/bin/Debug/Test.exe:10278): WARNING **: The following assembly referenced from /home/holland/Code/csharp/test/Test/bin/Debug/Test.exe could not be loaded:

如果我没记错的话,应该是一个汇编文件

这是我的代码:

using System;
using System.Collections;
using System.Collections.Generic;
using System.Data;
using MySql.Data.MySqlClient;

namespace Test
{
    public class Database
    {
        public Database()
        {

        }

        public static IDbConnection MainConnect()
        {
            string connectionInfo = 
            "Server=localhost;"+
            "Database=ecom_main;"+
            "User ID=root;"+
            "Password=xxxxxxx"+
            "Pooling=false;";

            return new MySqlConnection(connectionInfo);
        }
using System;
using System.Data;
using MySql.Data.MySqlClient;

namespace Test
{
    class MainClass
    {
        public static void Main (string[] args)
        {
            IDbConnection dbMain = Database.MainConnect();

            Console.WriteLine(dbMain);
        }
    }
}

解决方法:

我遇到了同样的问题,请按照以下步骤解决:

>使dll的副本大小写敏感:

   

#cp mysql.data.dll MySql.Data.dll

>安装连接器
  

#gacutil -i -package 2.0 MySql.Data.dll

这会安装在GAC中,并且还会在/usr/lib/mono/2.0中添加符号链接
>如果程序集未出现在monodevelop中,则可以将对项目中dll的引用添加到/usr/lib/mono/2.0
