将字符串转换为HttpPostedFileBase(Convert string to HttpPostedFileBase)

将字符串转换为HttpPostedFileBase(Convert string to HttpPostedFileBase)

我正在尝试使用MVC上传附件功能。 我实际上做上传/保存附件的方法是期待HttpPostedFileBase类型。

public virtual string Upload(HttpPostedFileBase fileName) { //Code to upload/save attachment. }

我的问题是“fileName”作为字符串从UI传递。 如何将字符串（文件路径名称）转换为我的Upload方法可以使用的内容。

提前致谢。

I am trying to do upload attachment functionality using MVC. My method that is actually doing the upload/save attachment is expecting a HttpPostedFileBase type.

public virtual string Upload(HttpPostedFileBase fileName) { //Code to upload/save attachment. }

My problem is "fileName" is being passed from the UI as a string. How can I convert the string(file path name) into something my Upload method can work with.

Thanks in advance.

正如其他人所提到的，你的表单应该是这样的：

<form id="form_UploadFile" action="" method="post" enctype="multipart/form-data"> <label for="file">Filename:</label> <input type="file" name="file" id="file" /> </form>

然后，正如你所提到的，你试图通过ajax发布，你可以使用jQuery serialize（）来序列化formData，并将其推送到你的控制器。

$('#form_UploadFile').serialize();

As mentioned by others, your form should look something like this:

<form id="form_UploadFile" action="" method="post" enctype="multipart/form-data"> <label for="file">Filename:</label> <input type="file" name="file" id="file" /> </form>

Then as you mentioned you are trying to post via ajax, you can use jQuery serialize() to serialize the formData to be pushed to your controller.

$('#form_UploadFile').serialize();
