来源：百度知道 编辑：UC知道 时间：2024/05/15 18:31:37
我是个菜鸟，在写程序时出现错误，路径中具有非法字符。怎么解决阿？！
String http = "//10.118.4.66:7021/dianneng/processuploadfile.jsp?sender_app=ecm&upload_date=2007.01.15&device_type=02&dm_type=02";
WebClient myWebClient = new WebClient();
string fileName = MIS.MisInfo.CurMidDBPath.ToString();//如d:\\111.txt
byte[] responseArray = myWebClient.UploadFile(http, "POST", fileName);
MessageBox.Show("上传文档成功！");
我改成"\\"还是出现“路径中具有非法字符”

1.windows的目录中允许出现的字符是有限定的，不允许出现的字符可以通过Path..GetInvalidFileNameChars()得到，下面是过滤目录中非法字符的方法：
string illegal = "\"M\"\\a/ry/ h**ad:>> a\\/:*?\"| li*tt|le|| la\"mb.?";
string invalid = new string(Path.GetInvalidFileNameChars()) + new string(Path.GetInvalidPathChars());
foreach (char c in invalid)
{
illegal = illegal.Replace(c.ToString(), "");
}
2.也可以使用正则表达式来做替换，如下代码：
string illegal = "\"M\"\\a/ry/ h**ad:>> a\\/:*?\"| li*tt|le|| la\"mb.?";
string regexSearch = new string(Path.GetInvalidFileNameChars()) + new string(Path.GetInvalidPathChars());
Regex r = new Regex(string.
