Description:

enum value is obsolete" is always shown during compilation.

How to repeat:
cmd.Parameters.Add("?dt", MySqlDbType.Datetime).Value = DateTime.Now

Hi Charles and thanks for your report.

Please take a minute to browse through c/NET changelog and you'll find this:
1. MySQL :: MySQL 5.1 Reference Manual :: C.3.17 Changes in MySQL Connector/NET 5.0.5 (07
March 2007)

    ... use of SchemaOnly or SingleRow command behaviors with stored procedures or
prepared statements. Added *MySqlParameterCollection.AddWithValue* and marked the
*Add(name, value) method as obsolete*. Return parameters created with DeriveParameters now
have the name 

This behavior is deliberate and documented so !Bg.

Example:
      MySqlCommand cmd = new MySqlCommand("fnTest", conn);
      cmd.CommandType = CommandType.StoredProcedure;

      //cmd.Parameters.Add("?valin", 22); << Obsolete
      cmd.Parameters.AddWithValue("?valin", 22); << Ok

      cmd.Parameters[0].DbType = DbType.Int32;
      cmd.Parameters[0].Direction = ParameterDirection.Input;

Hi,
   I believe you have misunderstood my post.  The issue that was raised has absolutely
nothing to do with the reply you have provided.  

To clarify, i code in both VB.NET and C#.  Codes in C# were compiled without warnings. 
Only codes in VB.net were getting the warning.  

The issue is VB.net, being case-insensitive does not differentiate between
"MySqlDbType.Datetime" and "MySqlDbType.DateTime" (Note the casing difference between the
Date"T"ime)

A patch for this bug has been committed. After review, it may
be pushed to the relevant source trees for release in the next
version. You can access the patch from:

Fixed in 5.1.7 and higher

An entry has been added to the 5.1.7 changelog:

As MySqlDbType.DateTime is not available in VB.Net the warning The datetime enum value is
obsolete was always shown during compilation.
