将图像文件打开到图片框中，使其成为位图
我希望能够在图片框中打开 .jpg、.gif 或 .bmp 并将其设为位图，以便我可以在其上绘图，但目前它会出现“参数无效”错误我运行我的程序，然后尝试将这些图像文件之一加载到我的图片框中。 这是我当前的代码：
openFileDialog1.InitialDirectory = @"N:\My Documents\My Pictures";
openFileDialog1.Filter = "JPEG Compressed Image (*.jpg|*.jpg" + "|GIF Image(*.gif|*.gif" + "|Bitmap Image(*.bmp|*.bmp";
openFileDialog1.Multiselect = true;
openFileDialog1.FilterIndex = 1;
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
capturebox.BackgroundImage = new Bitmap(ofd2.FileName);
}
我不知道为什么会发生这种情况，请帮忙。
谢谢
I want to be able to open either a .jpg, .gif or .bmp into a picturebox and make it a bitmap so i can draw on it, but at the moment it comes up with an error of 'Parameter is not valid' when i run my program and then try to load one of these image files into my picturebox.
This is my current code:
openFileDialog1.InitialDirectory = @"N:\My Documents\My Pictures";
openFileDialog1.Filter = "JPEG Compressed Image (*.jpg|*.jpg" + "|GIF Image(*.gif|*.gif" + "|Bitmap Image(*.bmp|*.bmp";
openFileDialog1.Multiselect = true;
openFileDialog1.FilterIndex = 1;
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
capturebox.BackgroundImage = new Bitmap(ofd2.FileName);
}
I don't know why this occurs, please help.
Thanks

您希望将倒数第二行的
ofd2替换为openFileDialog1。You want to replace
