You can use the Path API as follow

var fileName = System.IO.Path.GetFileNameWithoutExtension(*filePath*);

Try this

string filename = "file1.jpg";
string filenameonly=filename.Substring(0,filename.LastIndexOf('.'));

Here's a sample:

var fName = "test.1.jpg";
var noExt = fName.Remove(fName.LastIndexOf('.'), fName.Length - fName.LastIndexOf('.'));
Console.WriteLine(noExt);

The noExt variable contains the string you need.
