I'm going to reply to myself 😛

I got this far -- but the last piece having problems:

Code:

parameters = rs.GetItemParameters(report, historyID, forRendering, values, credentials);

Console.WriteLine("parameters[0].Name = " + parameters[0].Name);

Console.WriteLine("parameters[0].DefaultValues = " + parameters[0].DefaultValues);

The above 3 lines of code worked and I got the output:

parameters[0].Name = databaseName

parameters[0].DefaultValues =

Now All I want to do is to assign a Default Falue for this first parameter (parameters[0], databaseName) so I go:

rs.SetItemParameters(report, parameters[0].DefaultValues.SetValue("My_DB_Name", ???));

??For the '???' part no matter what I put (tried '2', 'parameters[0]' ) it wouldn't satisfy the complier -- keeps compalining "The best overloaded method match for 'System.Array.SetValue(object, params long[])' has some invalid arguments" ...

?Can someone give me some tips on WHAT should be inside the ( ) for SetValue ??? THAHK YOU SO MUCH!!!
