C#从listBox打开图像路径并在PictureBox中显示图像 [英] C# open image path from listBox and show image in PictureBox

问题描述

我有一个listBox，我在其中保存了Images的路径.我们将路径保存到sql数据库.这很好.我的问题是，有没有办法在其中一个路径上单击ListBox并在PictureBox中显示图像?在ListBox中使用鼠标单击事件会很好.

I have a listBox where I save paths from Images. We save the paths to sql Database. This works well. My question is, is there a way to click in ListBox on one of the paths and show the image in a PictureBox? Would be nice with a mouse click event in ListBox.

推荐答案

双击ListBox，它将为您创建一个新方法.

Double click on your ListBox and it should create you a new method.

粘贴此代码:

string path = listBox1.SelectedItem.ToString();

pictureBox1.Image = Image.FromFile(path);

就像吉米在评论中说的那样，以上代码将锁定文件.

Like Jimi said in the comments, the above code will lock the file.

改为使用此代码:

using (Bitmap tmpBitmap = new Bitmap(listBox1.SelectedItem.ToString()))
{
    pictureBox1.Image = new Bitmap(tmpBitmap);
}
