C#中实现文件拖放打开的方法

设置Form属性 AllowDrop = True;

在Form事件中

private void Form1_DragDrop(object sender, DragEventArgs e)        {            string localFilePath = ((System.Array)e.Data.GetData(DataFormats.FileDrop)).GetValue(0).ToString();//文件完整路径            string extension = System.IO.Path.GetExtension(localFilePath);//文件后缀名            if (extension == ".cbd")            { 　　　　　　　　//todo you code            }        }        private void Form1_DragEnter(object sender, DragEventArgs e)        {                       string localFilePath = ((System.Array)e.Data.GetData(DataFormats.FileDrop)).GetValue(0).ToString();            string extension = System.IO.Path.GetExtension(localFilePath);            if (string.Compare(extension, ".cds", true) == 0)            {                e.Effect = DragDropEffects.Move;            }            else            {                e.Effect = DragDropEffects.None;            }        }
