可以這樣做：

在程式碼目錄下新建upload資料夾

Controller：

[HttpPost]
public void Upload(HttpPostedFileBase img)
{
    Dictionary<string, object> result = new Dictionary<string, object>();
    try
    {
        img.SaveAs(Server.MapPath("~/upload/" + System.IO.Path.GetFileName(img.FileName)));
        result["path"] = "/upload/" + System.IO.Path.GetFileName(img.FileName);
    }
    catch (Exception ex)
    {
        result["error"] = ex.Message;
    }
    this.HttpContext.Response.Write(new JavaScriptSerializer().Serialize(result));
}
 

<form id="myForm" style="padding:20px;" action="Upload" method="post" enctype="multipart/form-data"></form>
<input name="img" style="width:350px;height:25px;" size="38" type="file" form="myForm" />

document.getElementById("myForm").submit();

B、只用HTML

<form id="myForm" style="padding:20px;" action="Upload" method="post" enctype="multipart/form-data">
	<input name="img" style="width:350px;height:25px;" size="38" type="file"/><input type="submit" value="上傳"/>
</form>
 

C、或者B+js

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.js"></script> 
<script src="http://malsup.github.com/jquery.form.js"></script> 

<script> 
    // wait for the DOM to be loaded 
    $(document).ready(function() { 
        // bind 'myForm' and provide a simple callback function 
        $('#myForm').ajaxForm(function() { 
            alert("succee"); 
        }); 
    }); 
</script> 
 

執行效果：
