为什么post 文件不能用

水瓶座

http://www.sufeinet.com/thread-9994-1-1.html
这是PHP代码
<?php
if ($_FILES["file"]["error"] > 0)
{
echo "Error: " . $_FILES["file"]["error"] . "<br />";
}
else
{
echo "Upload: " . $_FILES["file"]["name"] . "<br />";
echo "Type: " . $_FILES["file"]["type"] . "<br />";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
echo "Stored in: " . $_FILES["file"]["tmp_name"];
}
?>

C#
           string postfile = "C:\\Users\\admin\\Desktop\\POST.txt";
            //创建Httphelper对象
            http = new HttpHelper();
            //创建Httphelper参数对象
            item = new HttpItem()
            {
                URL = "http://localhost/1.php",//URL     必需项   
                Method = "post",//URL     可选项 默认为Get   
                ContentType = "application/x-www-form-urlencoded",//返回类型    可选项有默认值
                PostDataType = PostDataType.FilePath,
                Postdata = postfile
               


            };


返回的是PHP各种错误 用html文件来提交正常

首先你得贴出来一个错误信息看看，这个原因很复杂

正常的返回结果源码应该是：
Upload: POST.txt<br />Type: text/plain<br />Size: 0.6044921875 Kb<br />Stored in: C:\wamp\tmp\php5300.tmp

测试过程中感觉可能是post过去的时候post数据中 文件名不存在导致的

name="file"; 这里如果不是file 就会出问题
string dataFormat = boundary + "\r\nContent-Disposition: form-data; name=\"{0}\";filename=\"{1}\"\r\nContent-Type:application/octet-stream\r\n\r\n";

                string header = string.Format(dataFormat, "file", Path.GetFileName(file));
