在C#应用程序中使用OpenFileDialog控件 [英] Using the OpenFileDialog control in a C# application

问题描述

我确定我曾经问过这个问题，但是搜索什么也没做，我完全忘记了怎么做.

I'm sure I've asked this question before but searching does nothing and I completely forgot how to do this.

我需要一种方法，让用户从硬盘驱动器中选择图片，然后使用该位置将该图片加载到Image类中.

I need a way to have a user choose a picture from their hard drive and load that picture to an Image class using the location.

我过去曾经这样做过，但是正如我所说，我不记得自己是怎么做到的.

I've done this in the past, but as I said I can't remember how I did it.

我知道您可以将文件类型过滤器应用于OpenFileDialog.

I know you can apply a file type filter to the OpenFileDialog.

private void LoadImageToMemory()
        {
            openFileDialog1.Filter = "JPEG | jpeg";
            openFileDialog1.ShowDialog();            
        }

有指导吗?谢谢！

推荐答案

我知道了！

如果有人有相同的问题，这就是您的处理方法.

In case anyone has the same question, this is how you do it.

private void LoadImageToMemory()
        {
            openFileDialog1.Filter = "png files (*.png)|*.png|jpg files (*.jpg)|*.jpg";
            openFileDialog1.Multiselect = false;
            openFileDialog1.InitialDirectory = @"C:\";
            openFileDialog1.Title = "Select a picture to transform.";

            if (openFileDialog1.ShowDialog() == DialogResult.OK)
            {
                txtFileName.Text = openFileDialog1.FileName;
            }            
        }
