怎么在后面的image显示图片visual studio c# 语言来写

Answer 1

假设页面有按钮BtnShowImage，图片显示控件pbxShow ，BtnShowImage_Click
为BtnShowImage按钮的Click事件 则如下代码可以实现选择图片文件显示图片

        private void BtnShowImage_Click(object sender, EventArgs e)
        {
            OpenFileDialog openFileDialog = new OpenFileDialog();
            openFileDialog.InitialDirectory = "c:\\";
            openFileDialog.Filter = @"图像文件(JPeg, Gif)|*.jpg;*.jpeg;*.gif;*.bmp;*.png| JPeg 图像文件(*.jpg;*.jpeg)"
                + "|*.jpg;*.jpeg |GIF 图像文件(*.gif)|*.gif |BMP图像文件(*.bmp)|*.bmp|Png图像文件(*.png)"
                + "| *.png ";
            openFileDialog.RestoreDirectory = true;
            openFileDialog.FilterIndex = 1;

            if (openFileDialog.ShowDialog() == DialogResult.OK)
            {

                var fName = openFileDialog.FileName;

                Image img = Image.FromFile(fName);

                this.pbxShow.Image = img;

            }

        }
