+**方法一：Form表单提交**
+
+html代码：
+```html
+<!DOCTYPE html>
+<html>
+<head>
+  <meta charset="utf-8" />
+  <title>上传文件</title>
+  <script src="Scripts/jquery-1.11.3.min.js"></script>
+</head>
+<body>
+  <form action="UploadHandler.ashx" method="post" enctype="multipart/form-data">
+    <input id="file_upload" name="file_upload" type="file" />
+    <input id="btn_upload" type="submit" value="上传" />
+  </form>
+</body>
+</html>
+```
+
+UploadHandler.ashx代码：
+```c#
+using System;
+using System.Collections.Generic;
+using System.Linq;
+using System.Web;
+
+namespace WebApplication1
+{
+  /// <summary>
+  /// UploadHandler 的摘要说明
+  /// </summary>
+  public class UploadHandler : IHttpHandler
+  {
+    public void ProcessRequest(HttpContext context)
+    {
+      context.Response.ContentType = "text/plain";
+
+      HttpPostedFile file = context.Request.Files["file_upload"];
+      string filePath = context.Server.MapPath("~/UploadFiles/") + System.IO.Path.GetFileName(file.FileName);
+      file.SaveAs(filePath);
+
+      context.Response.Write("上传文件成功");
+    }
+
+    public bool IsReusable
+    {
+      get
+      {
+        return false;
+      }
+    }
+  }
+}
+```
+
+该方法虽然能够实现文件的上传，但是form表单提交之后整个页面就刷新了，如果要无刷新上传文件的话，就要使用ajax了。
+
+**方法二：jquery + ajax无刷上传**
+
+html代码：
+```html
+<!DOCTYPE html>
+<html>
+<head>
+  <meta charset="utf-8" />
+  <title>上传文件</title>
+  <script src="Scripts/jquery-1.11.3.min.js"></script>
+</head>
+<body>
+  <input id="file_upload" name="file_upload" type="file" />
+  <input id="btn_upload" type="button" value="上传" />
+
+  <script>
+    $(document).ready(function ()
+    {
+      $('#btn_upload').bind('click', function ()
+      {
+        var formData = new FormData();
+        formData.append('upload_file', $('#file_upload')[0].files[0]);
+        $.ajax({
+          url: 'UploadHandler.ashx',
+          type: 'post',
+          data: formData,
+          contentType: false,
+          processData: false,
+          success: function (msg)
+          {
+            if (msg == "Yes")
+            {
+              alert('文件上传成功');
+            }
+            else
+            {
+              alert('文件上传失败');
+            }
+          }
+        })
+      });
+    });
+  </script>
+</body>
+</html>
+```
+
+UploadHandler.ashx代码：
+```c#
+using System;
+using System.Collections.Generic;
+using System.Linq;
+using System.Web;
+
+namespace WebApplication1
+{
+  /// <summary>
+  /// UploadHandler 的摘要说明

+  public class UploadHandler : IHttpHandler
+  {
+
+    public void ProcessRequest(HttpContext context)
+    {

+
+      if (context.Request.Files.Count > 0)
+      {
+        HttpPostedFile file = context.Request.Files["upload_file"];
+        string filePath = context.Server.MapPath("~/UploadFiles/") + System.IO.Path.GetFileName(file.FileName);
+        file.SaveAs(filePath);
+        context.Response.Write("Yes");
+      }

+      }
+    }
