C#把外部文件拖入PictureBox中
不知道为何.net编辑器无法自动识别PictureBox的AllowDrop，属性列表中也没有，实际上他确实可以用。private void Form1_Load(object sender, EventArgs e) { //这句代码不会抱错，但是需要手动输入，.net编辑器无法自动识别AllowDrop this.pictureBox1.AllowDrop = true; } private void pictureBox1_DragDrop(object sender, DragEventArgs e) { string fileName = ((System.Array)e.Data.GetData(DataFormats.FileDrop)).GetValue(0).ToString(); this.pictureBox1.Image = Image.FromFile(fileName); } private void pictureBox1_DragEnter(object sender, DragEventArgs e) { if (e.Data.GetDataPresent(DataFormats.FileDrop)) e.Effect = DragDropEffects.Link; else e.Effect = DragDropEffects.None; }
