You need to change the way the request is made. Either complete your request string by adding ="" to the end, or leave out the BuildTypeName parameter when it is empty.

So you get either of these two cases:

/api/BuildTypeWebApi/GetBuildTypeList?CurrPage=1&PageSize=10&BuildTypeName=""

/api/BuildTypeWebApi/GetBuildTypeList?CurrPage=1&PageSize=10

This way, Web API actually knows what you want to do with the BuildTypeName parameter. In your case it was an incomplete request.
