### 通过指定连接属性参数打开数据库 ###

/// <param name="server">数据库服务器名</param>  
     /// <param name="instance">SDE的端口，默认安装时"port:5151"</param>  
     /// <param name="user">SDE的用户名</param>  
     /// <param name="password">密码</param>  
     /// <param name="database">数据库的名字</param>  
     /// <param name="version">SDE的版本</param>  
     /// <returns></returns>  
     public IWorkspace OpenSdeWorkspaceByPropertySet(string server, string instance, string user, string password, string database, string version)  
     {  
         IPropertySet Propset = new PropertySetClass();  
         Propset.SetProperty("SERVER", server);  
         Propset.SetProperty("INSTANCE", instance);  
         Propset.SetProperty("USER", user);  
         Propset.SetProperty("PASSWORD", password);  
         Propset.SetProperty("DATABASE", password);  
         Propset.SetProperty("VERSION", version);  
    
        IWorkspaceFactory workspaceFactory = new SdeWorkspaceFactoryClass();  
        return workspaceFactory.Open(Propset, 0);  
    }

### 通过连接字符串打开数据库 ###

/// <param name="connectionString">连接字符串</param>  
    /// For example, "SERVER=Kona;DATABASE=sde;INSTANCE=5151;USER=Editor;PASSWORD=Editor;VERSION=sde.DEFAULT"  
    /// <returns></returns>  
    public IWorkspace OpenSdeWorkspaceByConnectionString(string connectionString)  
    {  
        IWorkspaceFactory2 workspaceFactory = new SdeWorkspaceFactoryClass();  
        return workspaceFactory.OpenFromString(connectionString, 0);  
    }

### 通过sde文件打开数据库 ###

/// <param name="connectionFile">sde文件</param>  
    /// For example, "C:\\Data.sde"  
    /// <returns></returns>  
    public IWorkspace OpenSdeWorkspaceFromFile(string connectionFile)  
    {  
        IWorkspaceFactory workspaceFactory = new SdeWorkspaceFactoryClass();  
        return workspaceFactory.OpenFromFile(connectionFile, 0);  
    }
