if/else for fileUpload 문의 방법

Question

안녕하세요. 내 ASP.net 웹 페이지의 내 프로필 편집 페이지에서 내 fileupload 함수에 대한 if/else 문을 수행하려고합니다. 여기

내 코드입니다 : 내 파일 업로드 기능의 경우 다른 문을 사용하여 계획했던

protected void btnContinue_Click(object sender, EventArgs e) 
{ 
    //Declaration of variable to update Profile Image 
    string imageName, newContact; 
    imageName = FileUpload1.FileName.ToString(); 
    newContact = tbMobile.Text.ToString();

    MySqlDataAdapter sda = new MySqlDataAdapter("select * from pointofcontact where Username = '" + username.ToString() + "'", mcon); 
    DataTable dt = new DataTable(); 
    sda.Fill(dt); 
    if (dt.Rows.Count.ToString() == "1") 
    {

} 

같은 사용자가 새로운 사진을 업로드하지 않은 경우, 그/그녀는 여전히 업데이트 할 수있을 것이라고 그들의 프로필.

현재 사용자 프로필을 편집하려고하면이 오류 메시지가 나옵니다.

파일을 다른 디렉토리에 업로드하기 전에 파일을 저장하기 전에 다음 명령문을 사용하는 것이 좋습니다.

if (!Directory.Exists(Server.MapPath("~/Images"))) 
      Directory.CreateDirectory("~/Images"); 

이 라인

FileUpload1.PostedFile.SaveAs(Server.MapPath(Path.Combine("~/Images", imageName)));
