When i try 3 parameters with StringBuilder.AppendFormat it compiles ok.
How ever when i try with four or more parameters it gives the error message
[DCC Error] uUserSearch.pas(227): E2034 Too many actual parameters
The code I have used is
**************************************************
//strBldFile is of tyep StribgBuilder
srchFile.m_Contents := strBldFile.AppendFormat('{0} {1} {2} {3} 
','a','a','a','a').ToString.Trim;
*****************************************
I am using RS 2007 with Dec update in an asp.net application
The C# code compiles fine in VS
srchFile.Contents = strBldFile.AppendFormat("{0} {1} {2} {3}", 
srchFile.Contents, srchFile.Description, srchFile.Keywords, 
srchFile.Title).ToString().Trim();

It seems, that D.Net still has no support for the ParamArrayAttribute. Thus you have to pass these 
arguments as an inline array.
sb.ApendFormat('{0} {1} {2} {3}',
                ['a', 'b', 'c', 'd']);

Funny though, you already did it in the other post of yours (the one with the escape sequences).

I think they just chose to implement it in a way that was more
consistent with other variable parameter methods like System.Format.

The reason it works with up to 3 parameters is that AppendFormat is
overloaded.

The last parameter is marked with [ParamArray], which usually means that you can provide these values 
as if they were parameters, instead of an array.
