C#-从流中读取文件

我已经发送了一个XML和一个Text文件,在Web服务中,我将其读取如下：

StreamReader stream = new StreamReader(HttpContext.Current.Request.InputStream);
string xmls = stream.ReadToEnd(); 

我将流作为字符串获取,如下所示(我还添加了边界)：

"\r\n------------------------------8cfd42d26566ff0\r\nContent-Disposition: form-data; name=\"uplTheFile\"; filename=\"E:\\AJ\\Demo\\EktronSite2\\XMLFiles\\XMLFile.xml\"\r\n Content-Type: application/octet-stream\r\n\r\n<?xml version=\"1.0\" encoding=\"utf-8\"?>\r\n<note xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns=\"http://tempuri.org/XMLFile.xsd\">\r\n  <ID>101</ID>\r\n</note>\r\n------------------------------8cfd42d26566ff0\r\nContent-Disposition: form-data; name=\"uplTheFile\"; filename=\"C:\\TEMP\\log.txt\"\r\n Content-Type: application/octet-stream\r\n\r\nABCDEFGHIJKLMNOPQRSTUVWXYZ\r\n------------------------------8cfd42d26566ff0\r\n"

我需要将相同的内容读入不同的文件中.例如,我需要将XML读取为XmlDocument类型,将文本读取为.docx.

提前致谢.

Stream xmlStream = System.Web.HttpContext.Current.Request.Files[0].InputStream;
Stream txtStream = System.Web.HttpContext.Current.Request.Files[1].InputStream;
