The SQLCommandBuilder has the helpful DeriveParameters command that gives you the list of parameters of a stored procedure. All you have to do is:

1. Set the commandText of the command object to the StoredProcedure Name
2. Set the CommandType of the command object to “StoredProcedure”
3. Use the SqlCommandBuilder’s DeriveParameters command to retrieve the list of parameters.

Code sample:

SqlCommand myCommand; myCommand.CommandType = CommandType.StoredProcedure; myCommand.CommandText = storedProcedureName; ...SqlCommandBuilder.DeriveParameters(myCommand); 

Use the Command’s parameters list to retrieve them.
