如何使用右键菜单项到图片框 [英] How to use right click menu item to a picture box
问题描述
当我右键单击图片框时，通过使用上下文菜单项，我显示了像saveImageAs这样的标签。
问题：当我右键单击图片框时，它会显示saveImageAs，当我点击saveImageAs时我会点击
private void saveImageAsToolStripMenuItem_Click（对象发件人，EventArgs e）
{
//我应该使用什么而不是点击来点击form_Mouseclick
pictureBox1.Click + = form_MouseClick;
pictureBox2.Click + = form_MouseClick;
}
这里我应该使用什么代替pictureBox1.click才能点击form_MouseClick
如果有人可以提供帮助，我会非常感激。
private void saveImageAsToolStripMenuItem_Click（object sender，EventArgs e）
{
pictureBox1.Click + = form_MouseClick;
pictureBox2.Click + = form_MouseClick;
}
private void form_MouseClick（对象发送者，MouseEventArgs e）
{
PictureBox pb =发送者作为PictureBox;
SaveFileDialog sfd = new SaveFileDialog（）;
sfd.Filter =Images | * .png; * .bmp; *。jpg;
if（sfd.ShowDialog（）== System.Windows.Forms.DialogResult .OK）
{
string filepath = System.IO.Path.GetExtension（sfd.FileName）;
}
if（pb！= null&& sfd.FileName！= null）
{
Image im = pb.Image;
SaveImage（im，sfd.FileName）;
}
} $ / $
private static void SaveImage（Image im，string destPath）
{
im.Save（destPath） ，System.Drawing.Imaging.ImageFormat.Png）;
}
我尝试了什么：
我试过
private void saveImageAsToolStripMenuItem_Click（object sender，EventArgs e）
{
pictureBox1.MouseClick + = form_MouseClick;
pictureBox2.MouseClick + = form_MouseClick;
}
when I right-click on a picturebox, by using context menu items i am showing the labels like saveImageAs.
problem: when i right click on a picture box, it shows saveImageAs, when i click saveImageAs i will hit
private void saveImageAsToolStripMenuItem_Click(object sender, EventArgs e)
{
//what should i use instead of click to hit form_Mouseclick
pictureBox1.Click += form_MouseClick;
pictureBox2.Click += form_MouseClick;
}
here what should i use instead of pictureBox1.click to hit form_MouseClick
If anyone could help I would be most greatful.
private void saveImageAsToolStripMenuItem_Click(object sender, EventArgs e)
{
pictureBox1.Click += form_MouseClick;
pictureBox2.Click += form_MouseClick;
}
private void form_MouseClick(object sender, MouseEventArgs e)
{
PictureBox pb = sender as PictureBox;
SaveFileDialog sfd = new SaveFileDialog();
sfd.Filter = "Images|*.png;*.bmp;*.jpg";
if (sfd.ShowDialog() == System.Windows.Forms.DialogResult.OK)

SaveImage(im, sfd.FileName);
}
}
private static void SaveImage(Image im, string destPath)

推荐答案
你必须检查你的MouseClick-Method按下/使用哪个MouseButton。
为此你可以使用e.Button：
You must check in your MouseClick-Method which MouseButton was pressed/used.
For this you can use e.Button :
if (e.Button == Windows.Forms.MouseButtons.Right) { }
