Question

 var dlg = new Microsoft.Win32.OpenFileDialog();
        dlg.Filter = "(*.JPG;*.GIF)|*.JPG;*.GIF";
        dlg.ShowDialog();
        if (string.IsNullOrEmpty(dlg.FileName)) return;
        var fs = new FileStream(dlg.FileName, FileMode.Open, FileAccess.Read);
        var data = new byte[fs.Length];
        fs.Read(data, 0, System.Convert.ToInt32(fs.Length));
        fs.Close();

我正在使用此代码但未找到如何查找图像的大小或尺寸？

Answer 1

作为此问题的一部分回答：Limit image size

string filename = // get it from OpenFileDialog
var length = new FileInfo(filename).Length;
Image img = Image.FromFile(filename);
var w = img.Width;
var h = img.Height;

Answer 2

使用FileInfo给定此文件的路径并使用Length作为

var dlg = new Microsoft.Win32.OpenFileDialog();
dlg.Filter = "(*.JPG;*.GIF)|*.JPG;*.GIF";
dlg.ShowDialog();

if (string.IsNullOrEmpty(dlg.FileName)) 
  return;

FileInfo info = new FileInfo(dlg.FileName);
Console.Write("Length In Bytes:"+info.Length);
