Httpwebrequest失败,找不到错误:Windows Phone 8

我试图从Windows Phone 8发布一个httpwebrequest到Rest服务,http头:User-agent = @"Mozilla/5.0(兼容; MSIE 10.0; Windows Phone 8.0; Trident/6.0; IEMobile/10.0; ARM;触摸;微软;虚拟)"和帖子帖体:payload = testvalue&item1 = value;

从REST客户端发布时,相同的请求会返回响应

以下是Windows Phone 8代码中出现的异常

使用太多内存读取文件流

我想将一个文件base64string读入流中作为一个并且我使用下面的代码来读取文件,但是当我看到内存使用量超过900MB时,我通过任务管理器监视它.我错过了什么,我可以看到当我将其读入字符串时,内存使用率会上升,(我已经使用了150 MB的文件来测试它).

stringBuilder Sb=  new stringBuilder ();
using (var fs = new FileStream(@"C:\Users\Sanath Kumar\Desktop\s.pdf", FileMode.Open, FileAccess.Read))
{
    var buffer = new byte[fs.Length];
    fs.Read(buffer, 0, (int)fs.Length);
    Sb.Append(Convert.ToBase64String(buffer));
    buffer = null;
    fs.Flush();
    fs.Dispose();
}
