C#获取文件名和文件路径的两种方法

方法一

OpenFileDialog open = new OpenFileDialog();
open.RestoreDirectory = true;
string fullname = open.FileName;
string path = System.IO.Path.GetDirectoryName(fullname);//路径
string name = System.IO.Path.GetFileName(fullname);//名称

方法二

OpenFileDialog open = new OpenFileDialog();
open.RestoreDirectory = true;
string fullpath = open.FileName;
//获取文件路径和文件名
int index = fullpath.LastIndexOf("//");  //返回“//”最后一次出现的位置
string filepath = fullpath.Substring(0,index); //截取字符串，0到“//”最后出现的位置
string filename = fullpath.Substring(index+1);  //截取文件名
