string linksfile;
string [] excelfile = Directory.GetFiles(Application.StartupPath + @"\", "*.xlsx");
linksfile = excelfile[0];

MessageBox.Show(linksfile);

    string [] excelfile = Directory.GetFiles(Application.StartupPath + @"\", "*.xlsx");

    if(excelfile.Length > 0)
    {
        linksfile = excelfile[0];

        MessageBox.Show(linksfile);
    }
    else
    {
         MessageBox.Show("File not found");
    }
