Sql vb.net服务器连接重载

我正在尝试运行此代码，但它显示错误重载解析失败

Conn = New OleDbConnection(ConnectionString)    
Dim serverConn As New Server(New ServerConnection(Conn))

以下是全部错误：

Overload resolution failed because no accessible 'New' can be called with these arguments:
'Public Sub New(serverInstance As String)': Value of type 'System.Data.OleDb.OleDbConnection' cannot be converted to 'String'.
'Public Sub New(sqlConnection As System.Data.SqlClient.SqlConnection)': Value of type 'System.Data.OleDb.OleDbConnection' cannot be converted to 'System.Data.SqlClient.SqlConnection'.
'Public Sub New(sci As Microsoft.SqlServer.Management.Common.SqlConnectionInfo)': Value of type 'System.Data.OleDb.OleDbConnection' cannot be converted to 'Microsoft.SqlServer.Management.Common.SqlConnectionInfo'.

如果要管理MS SQL Server，则需要SqlConnection，而不是通用OLEDB连接

用SqlConnection替换OleDbConnection，或者将ConnectionString直接传递到新服务器，而不首先实例化显式连接
