Question

我是视觉C＃的新手我想在图片框中显示一系列图像

这是我的代码：

string[] list = Directory.GetFiles(@"C:\\pictures", "*.jpg");

Image[] images = new Image[5];

for (int index = 0; index < 5; index++)
{
    images[index] = Image.FromFile(list[index]);
}

当我运行它时，图片框是空白的。

添加表单级变量：

private int selectedImageIndex = -1;   // to store the active index in the images array

添加一个带有点击事件处理程序的按钮：

selectedImageIndex++;  // increment the active index
// if the active index is equal to the image count we've gone past the end of the array, so loop back to the beginning.
if (images.Count == selectedImageIndex) { selectedImageIndex = 0; }
pictureBox.Image = images[selectedImageIndex];  // assign the selected image to the picturebox

在picturebox中显示图像数组
