通过传递文件路径来上传文件。。。出问题了。。。。。。

Question

我用 stream 上传图片。。之前用好好的。。
但是最近出现问题 
说是未能找到路径 "c"\1.jpg"  这个路径是客户端的文件路径
请问是怎么回事？
之前用好好的。。我想应该是权限问题。后来我把目标文件夹 和 c:\windows\temp全加了 everyone权限也还不行。
代码是/// <summary>
        /// 通用的上传图片函数
        /// </summary>
        /// <param name="FileName">需要上传的文件路径（客户端）</param>
        /// <param name="path">要上传的地址（服务器端）</param>
        /// <param name="authorization">这个不要问。我都用的FALSE</param>        /// <returns>上传服务器的文件名</returns>
        /// 
        public static string tt66w_UploadPic(string FileName, string path, bool authorization)
        {
            if (FileName != "")
            {
                string FilePath = null;
                string File_Name = null;
                Random rd = new Random();

                string fileExtname = FileName.Substring(FileName.LastIndexOf(".") + 1);
                fileExtname = fileExtname.ToLower();
                if (authorization)
                {
                    return "";

                else

Answer 1

你这是文件路径吗 
"c"\1.jpg"
应该是
"c:\\1.jpg"

Answer 2

后来我看了
http://www.cnblogs.com/xyd21c/archive/2011/07/14/2106598.html
这个文章。。然后把将FileStream fs = new FileStream(upFileName, FileMode.Open, FileAccess.Read, FileShare.Read);替换为Stream fs = new StreamReader(upFileName);
但是提示 错误  StreamReader无法转换为  stream 
但是文章里为什么说要这么换？？？是不是中间少了几部？？？？？？请高手指导孟大哥你来帮帮忙
