winform 上传文件 实例源码

工作中用到winform上传文件（-_-!，很少用winform，搞了半天）
碰到一点问题，解决如下
1、501 为实现错误
解决方法：
先把IISWEB服务扩展中的WebDev打开
然后
IIS站点添加MIME  txt类型 常见的MIME类型如下
超文本标记语言文本 .html,.htmltext/html
普通文本 .txt text/plain
RTF文本 .rtfapplication/rtf
GIF图形 .gif image/gif
JPEG图形 .ipeg,.jpgimage/jpeg
au声音文件 .au audio/basic
MIDI音乐文件 mid,.midiaudio/midi,audio/x-midi
RealAudio音乐文件 .ra, .ramaudio/x-pn-realaudio
MPEG文件 .mpg,.mpegvideo/mpeg
AVI文件 .avivideo/x-msvideo
GZIP文件 .gzapplication/x-gzip
TAR文件 .tarapplication/x-tar
再然后
设置目标文件夹的可写性
