OpenFileDialog C#自定义过滤器,如'ABC*.pdf'

Question

是否可以指定自定义过滤器,如'ABC*.pdf',这意味着:"显示所有以ABC开头的PDF"？

我只能指定*.pdf,*.doc , . 等

谢谢弗洛里安

Changed my solution a little, after realizing the following would be better. This is not a complete "hard filter", but making use of the FileName property should basically give you what you need;

using System;
using System.Windows.Forms;

namespace TestingFileOpenDialog
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            this.openFileDialog1.FileName = "pro*";
            this.openFileDialog1.Filter = "Pdf Files|*.pdf";
            this.openFileDialog1.ShowDialog();
        }
    }
}

I suppose this might depend on which OS you are working with, but it did work in my case any way, on Windows 8.

I also realize that this does not filter out all irrelevant files "permanently", but it does at least provide an initial filter.

Result:

如果没有pro*在FileName字段中,这将显示其他几个PDF文件.
