如何從OpenFileDialog獲取文件大小？

Question

如何在我的Openfiledialog中獲取當前選定文件的文件大小？

Answer 1

var ofd = new OpenFileDialog(); 
if (ofd.ShowDialog() == DialogResult.OK) 
{ 
    var size = new FileInfo(ofd.FileName).Length; 
} 

Answer 2

有這麼稀疏的信息我能告訴你的是：

new FileInfo(dialog.Filename).Length 

Answer 3

if (this.myOpenFileDialog.ShowDialog() == DialogResult.OK) 
{ 
    var length = new System.IO.FileInfo(this.myOpenFileDialog.FileName).Length; 
}
