我是c#.net的新手,任何人都让我知道如何在C#Windows中获取文件大小,文件名,文件扩展名.

即时通讯使用c#中的打开文件对话框我只获取路径..我不知道如何获取文件名和大小..

我的代码是:

openFileDialog1.ShowDialog();

openFileDialog1.Title = "Select The File";
openFileDialog1.InitialDirectory = "C:";
openFileDialog1.Multiselect = false;
openFileDialog1.CheckFileExists = false;

if (openFileDialog1.FileName != "")
 {
  txtfilepath1.Text = openFileDialog1.FileName;
  var fileInfo = new FileInfo(openFileDialog1.FileName);
  lblfilesize1.Text = Convert.ToString(openFileDialog1.FileName.Length);  

  lblfilesize=
  lblfilename=    
 }

我的代码:

public void FillMaxBankCode()
{
    try
    {
        DataSet ds = new DataSet();
        ds = bol.SelectMaxBankCode();
        string j = ds.Tables[0].Rows[0].ToString();
        txtbankid.Text = int.Parse(j); //ERROR HERE
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
}



  public DataSet SelectMaxBankCode()
    {
        try
        {
            **Squery = "EXEC SelectMaxBankCode";**
            return dal.DBread(Squery);
        }
        catch (Exception ex)
        {
            throw ex;
        }
    }

我是C#的新手,上面的代码显示错误..任何人都可以帮忙吗？
