我在这里有一个问题，我知道这对你来说很简单，但实际上我需要了解它是做什么的，一行一行的。

using (var stream = new MemoryStream())
{
    var context = (System.Web.HttpContextBase)Request.Properties["MS_HttpContext"];
    context.Request.InputStream.Seek(0, SeekOrigin.Begin);
    context.Request.InputStream.CopyTo(stream);
    strContent = Encoding.UTF8.GetString(stream.ToArray());
    AppLog.Write("Request content length: " + strContent.Length);
}

Api MemoryStream c#，这个代码是如何工作的

// create a MemoryStream to act as a buffer for some unspecified data
using (var stream = new MemoryStream())
{
    // obtain the http-context (not sure this is a good way to do it)
    var context = (System.Web.HttpContextBase)Request.Properties["MS_HttpContext"];
    // reset the context's input stream to the start
    context.Request.InputStream.Seek(0, SeekOrigin.Begin);
    // copy the input stream to the buffer we allocated before
    context.Request.InputStream.CopyTo(stream);
    // create an array from the buffer, then use that array to
    // create  a string via the UTF8 encoding
    strContent = Encoding.UTF8.GetString(stream.ToArray());
    // write the number of characters in the string to the log
    AppLog.Write("Request content length: " + strContent.Length);
}

请注意，实际上这里的每件事都可以做得更有效率。
