flag.initialdirectory = “d:\\”; //设置初始路径
flag.filter = “csv files (*.csv)|*.csv|all files (* .*)|* .*”; //设置“另存为文件类型”或“文件类型”框中出现的选择内容
flag.restoredirectory = true; //设置对话框是否记忆上次打开的目录

{
strpath = flag.filename;
messagebox.show(strpath);
}

saveflag.addextension = true;//设置自动在文件名中添加扩展名
saveflag.filter = “csv files (*.csv)|*.csv|all files (* .*)|* .*”;
saveflag.restoredirectory = true;
if (saveflag.showdialog() == dialogresult.ok)
{
