Entity Framework อ่าน ConnectionString จาก Model Entities ที่เชื่อมต่ออยู่ได้ยังไงครับ

    using System.Data.EntityClient;

    private string GetADOConnectionString()
    {
        DBEntities ctx = new DBEntities(); //create your entity object here
        EntityConnection ec = (EntityConnection)ctx.Connection;
        SqlConnection sc = (SqlConnection)ec.StoreConnection; //get the SQLConnection that your entity object would use
        string adoConnStr = sc.ConnectionString;
        return adoConnStr;
    }

Private Function GetADOConnectionString() As String
	Dim ctx As New DBEntities()
	'create your entity object here
	Dim ec As EntityConnection = DirectCast(ctx.Connection, EntityConnection)
	Dim sc As SqlConnection = DirectCast(ec.StoreConnection, SqlConnection)
	'get the SQLConnection that your entity object would use
	Dim adoConnStr As String = sc.ConnectionString
	Return adoConnStr
End Function
