This works in VB.Net but cant figure out what's wrong in C# with this. (new to C#).

1. I have a class like this in my DAL :
namespace Uni.DIAL.IDAL.Common {
 public sealed class DBTools
    {
       private static DataProvider _DBType;
        public static DataProvider DBType
        {
            get { return _DBType; }
            set { _DBType = value; }
        }
   
    }
}

2. In my Presenation layer I have:
class CheckPCALL
    {
        public enum DataProvider
        {
            SqlServer, OleDb, Odbc, IBM
        }
        static void Main(string[] args)
        {
           //Console.Write("Hello");
                Uni.DIAL.IDAL.Common.DBTools.DBType =  DataProvider.SqlServer;
                      }
    } //end of class

*** I get the Cannot implicitly convert type 'Uni.DIAL.DispositionNumber.CheckPCALL.DataProvider' to 'DataProvider'. An explicit conversion exists (are you missing a cast?)

*** I found http://www.csharp-station.com/Tutorials/Lesson17.aspx and added an int to it but no.

How can I fix this??

Uni.DIAL.IDAL.Common.DBTools.DBType = (Uni.DIAL.IDAL.Common.DBTools.DBType) DataProvider.SqlServer;


You need convert c# doesnot accept as variant as in vb or asp

May be you define custom enum  if required

eh, i did have it defined somewhere else. I was copying from VB.Net and pasting to C#. Got an error , and copied the enum somewhere else and forgot to take that one out...

but is Maverick correct? I have "Uni.DIAL.IDAL" at the top of the class...so maybe that's why DataProvider.SQLServer works without specifying the class?

If the type of the DBType property is an enum, you should use one of the items from that enum.

If you create your own enum and cast to another enum, the value will be converted directly without matching the names of the enums. If the items of the enums are not specified in the exact same order, you will get the wrong value. Also, if the definition of either enum changes so that they don't match any more, you will not get any warning when compiling.
