PictrueBox过滤器

 

往PictrueBox里面添加图片的时候往往要过滤掉非图片格式的文件，方便操作。

 

private void button1_Click(object sender, EventArgs e)
{
      try
       {
             OpenFileDialog openfileDialog = new OpenFileDialog();

             //这一段就是PictrueBox过滤器
             openfileDialog.Filter = "Image files (JPeg, Gif, Bmp, etc.)|*.jpg;*.jpeg;*.gif;*.bmp;*.tif; *.tiff; *.png|" +
             "JPeg files (*.jpg;*.jpeg)|*.jpg;*.jpeg |GIF files (*.gif)|*.gif |BMP files (*.b" +
             "mp)|*.bmp|Tiff files (*.tif;*.tiff)|*.tif;*.tiff|Png files (*.png)| *.png |All f" +
             "iles (*.*)|*.*";

              if ((openfileDialog.ShowDialog() == System.Windows.Forms.DialogResult.OK))
               {
                    this.pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage;
                    this.pictureBox1.ImageLocation = openfileDialog.FileName;
                }
         }
         catch (Exception ex)
         {
             MessageBox.Show(ex.Message.ToString(), "提示信息", MessageBoxButtons.OK, MessageBoxIcon.Information);
          }

}
