Microsoft SQL Server 2014 over Network.Oledb 连接字符串

我找不到与Microsoft SQL服务器的合适连接字符串，这是2014开发人员版本。我目前的提供者是这样的：

string strAccessConn = "Provider=SQLNCLI11;Data Source=10.211.55.7;Network Library=DBMSSOCN;Initial Catalog=myDataBase;User Id=pos;Password=password;";

但是，我收到此错误，错误

作为参考，这是我的源代码。

string strAccessConn = "Provider=SQLNCLI11;Data Source=10.211.55.7,1433;Network Library=DBMSSOCN;Initial Catalog=myDataBase;User Id=pos;Password=password;";
string strAccessSelect = "SELECT userid FROM users";
DataSet myDataSet = new DataSet();
OleDbConnection myAccessConn = null;
try
{
    myAccessConn = new OleDbConnection(strAccessConn);
}
catch (Exception ex)
{
    Console.WriteLine("Error: Failed to create a database connection. 'n{0}", ex.Message);
    Console.ReadLine();
}
try
{
    OleDbCommand myAccessCommand = new OleDbCommand(strAccessSelect, myAccessConn);
    OleDbDataAdapter myDataAdapter = new OleDbDataAdapter(myAccessCommand);
    myAccessConn.Open();
    myDataAdapter.Fill(myDataSet, "Police");
}
catch (Exception ex)
{
    Console.WriteLine("Error: Failed to retrieve the required data from the DataBase.'n{0}", ex.Message);
    Console.ReadLine();
    return;
}
finally
{
    myAccessConn.Close();
}

我想使用 OleDbConnector。

谢谢！
