将一个文件拖拽到窗体的某个控件时,将该控件的路径显示在该控件上,只要拿到了路径自然可以读取文件中的内容了
将一个控件的属性AllowDrop设置为true,然后添加DragDrop、DragEnter时间处理函数,如下:
private void txtAppPath_DragEnter(object sender, System.Windows.Forms.DragEventArgs e) { if (e.Data.GetDataPresent(DataFormats.FileDrop)) { e.Effect = DragDropEffects.Link; } else { e.Effect = DragDropEffects.None; } } private void txtAppPath_DragDrop(object sender, System.Windows.Forms.DragEventArgs e) { txtLocalFileName.Text = ((System.Array)e.Data.GetData(DataFormats.FileDrop)).GetValue(0).ToString(); }
private void button1_Click(object sender, EventArgs e) { // System.Diagnostics.Process.Start("Explorer.exe", "c:\\windows"); System.Diagnostics.Process.Start("Explorer.exe", this.button1.Text); }
