Advice+Help for C# SQL Server project

I am an experienced Perl software developer. I am working at home as a hobby on a small C# and SQL Server project. I know how to design and develop software but have no practical experience of C# (especially OO programming). I have SQL Server experience. I even have an MCSD where I passed the C# Windows, ASP.NET and Web programming exams, so I have some idea. However I keep being stymied for hours because C# doesn't let me do things I can do in Perl. I am looking for somebody who is close to the Australian East Coast timezone (GMT+10), who is ready to receive emails from me and give me a quick reply how to fix my problem or where to look to learn how to fix my problem. The budget is USD60 and I expect to pay for each email USD5-10 (more if needed), depending on the difficulty of my question. Typical question: Why does string typeString = (string)dr[2].GetType(); if (typeString == "[login to view URL]") not work? (dr is a datarow in a datatable received from an SQL dataset. I want to test whether a column in that row contains a null value.) ## Deliverables Answering 6 - 12 emails of mine, preferably with an answer I can use. ## Platform C# and ADO using Visual Studio [login to view URL] professional edition and SQL Server 2005 developer edition.
