try:

string fileName = @"test.txt";
    string currentDirectory = Directory.GetCurrentDirectory();
    string[] fullFilePath = Directory.GetFiles(currentDirectory, filename, SearchOption.AllDirectories);

it will return full path of all such files in the current directory and its sub directories to string array fullFilePath. If only one file exist it will be in "fullFileName[0]".
