NBear3.7移植到 Mono2 笔记

准备：在 OpenSuse11 下搭建了 MONO2 环境 ，更新系统，把能打的补丁全打上，这样可以启用 debugger 。

1. windows 上的 System.Data.Sqlite 不能正常加载。去除，添加 mono.data.sqlite .
2. Mono 没有完全实现 System.Data.dll 中的所有类。新建两个类：

// OleDbFacroty.cs created with MonoDevelop
// User: xh at 下8:02 08-12-29
//
// To change standard headers go to Edit->Preferences->Coding->Standard Headers
//

using System;
using System.Data;
using System.Data.Common;
using System.Data.OleDb;
using System.Security;
using System.Security.Permissions;

namespace NBear.Data.Mono
{
    public  class OleDbFactory : System.Data.Common.DbProviderFactory
    {
        // Fields
        public static readonly OleDbFactory Instance = new OleDbFactory();
    
        // Methods
        private OleDbFactory()
        {
        }
    
        public override DbCommand CreateCommand()
        {
            return new OleDbCommand();
        }
    
        public override DbCommandBuilder CreateCommandBuilder()
        {
            return new OleDbCommandBuilder();
        }
    
        public override DbConnection CreateConnection()
        {
            return new OleDbConnection();
        }
    
        public override DbConnectionStringBuilder CreateConnectionStringBuilder()
        {        
            throw new Exception("MONO 不能实现 OleDbFactory.CreateConnectionStringBuilder ！！！") ;
            //return new OleDbConnectionStringBuilder();
        }
    
        public override DbDataAdapter CreateDataAdapter()
        {
            return new OleDbDataAdapter();
        }
    
        public override DbParameter CreateParameter()
        {
            return new OleDbParameter();
        }

        public override CodeAccessPermission CreatePermission(PermissionState state)
        {
            return new OleDbPermission(state) ;
        }

        
    }
}

// OracleClientbFacroty.cs created with MonoDevelop
// User: xh at 下8:02 08-12-29
//
// To change standard headers go to Edit->Preferences->Coding->Standard Headers
//

using System;
using System.Data;
using System.Data.Common;
using System.Data.OleDb;
using System.Security;
using System.Security.Permissions;
using System.Data.OracleClient;

namespace NBear.Data.Mono
{
    public  class OracleClientFactory : System.Data.Common.DbProviderFactory
    {
           // Fields
        public static readonly OracleClientFactory Instance = new OracleClientFactory();
    
        // Methods
        private OracleClientFactory()
        {
        }
    
        public override DbCommand CreateCommand()
        {
            return new OracleCommand();
        }
    
        public override DbCommandBuilder CreateCommandBuilder()
        {
            return new OracleCommandBuilder();
        }
    
        public override DbConnection CreateConnection()
        {
            return new OracleConnection();
        }
    
        public override DbConnectionStringBuilder CreateConnectionStringBuilder()
        {
            throw new Exception("MONO 不能实现 OracleClientFactory.CreateConnectionStringBuilder ！！！") ;
            //return new OracleConnectionStringBuilder();
        }
    
        public override DbDataAdapter CreateDataAdapter()
        {
            return new OracleDataAdapter();
        }
    
        public override DbParameter CreateParameter()
        {
            return new OracleParameter();
        }
    
        public override CodeAccessPermission CreatePermission(PermissionState state)
        {
            return new OraclePermission(state);
        }
    }
}

3。在找不到 ProviderFactory.Instance 的地方，添加 using NBear.Data.Mono ;

4。基本上就可以了。App.Config 不能正常配置，只能硬编码 Gateway 。

Gateway g = DbConfig.TheOne;

            Dict d =  g.Find<Dict>(Dict._.ID == 3 ) ;

            Console.WriteLine( d.Value  ) ;
