做一个技巧
code> bool heldImage = false;
控制currentControl = null;
private void pictureBox1_MouseDown(object sender,MouseEventArgs e)
{
heldImage = true;
}
private void pictureBox2_MouseEnter(object sender,EventArgs e)
{
currentControl = pictureBox2;
}
private void pictureBox2_MouseLeave(object sender,EventArgs e)
{
currentControl = null;
}
private void pictureBox1_MouseUp(object sender,MouseEventArgs e)
{
if(heldImage&& currentControl == pictureBox2)
{
pictureBox2.Image = pictureBox1.Image;
pictureBox1.Image = null;
}
heldImage = false;
currentControl = null;
}
问题是我无法在PictureBox中找到AllowDrop属性,否则会轻松实现 DoDragDrop()

Upadated:Do a trick
bool holdsImage = false;
Control currentControl = null;
private void pictureBox1_MouseDown(object sender, MouseEventArgs e)
{
holdsImage = true;
}
private void pictureBox2_MouseEnter(object sender, EventArgs e)
{
currentControl = pictureBox2;
}
private void pictureBox2_MouseLeave(object sender, EventArgs e)
{
currentControl = null;
}
private void pictureBox1_MouseUp(object sender, MouseEventArgs e)
{
if (holdsImage && currentControl==pictureBox2)
{
pictureBox2.Image = pictureBox1.Image;
pictureBox1.Image = null;
}
holdsImage = false;
currentControl = null;
}
Problem is that I am unable to find AllowDrop property in PictureBox else it will be easy to implement by DoDragDrop()
