Match Function For Cell Reference Row Number

I am trying to acccess a cell value from a seperate worksheet. The cell reference needs to be generated by a seperate formula. In this example

=DSInfo!C28 // provides the correct result i.e the contents of cell C28 on worsheet DSInfo =MATCH(A4,DSInfo!C1:C35,0) //provides the correct row number - in this case 28

However on trying to combine the two =DSInfo!C&MATCH(A4,DSInfo!C1:C35,0) // provides only a formula error. I'm guessing this is a simple syntax error on my part but after hours of trying various ways I'm still having no luck.
