ASP.NET MVC File Upload Error - "The input is not a valid Base-64 string"
- by Justin
Hey all,
I'm trying to add a file upload control to my ASP.NET MVC 2 form but after I select a jpg and click Save, it gives the following error:
The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or a non-white space character among the padding characters.
Here's the view:
<% using (Html.BeginForm("Save", "Developers", FormMethod.Post, new {enctype = "multipart/form-data"})) { %>
<%: Html.ValidationSummary(true) %>
<fieldset>
<legend>Fields</legend>
<div class="editor-label">
Login Name
</div>
<div class="editor-field">
<%: Html.TextBoxFor(model => model.LoginName) %>
<%: Html.ValidationMessageFor(model => model.LoginName) %>
</div>
<div class="editor-label">
Password
</div>
<div class="editor-field">
<%: Html.Password("Password") %>
<%: Html.ValidationMessageFor(model => model.Password) %>
</div>
<div class="editor-label">
First Name
</div>
<div class="editor-field">
<%: Html.TextBoxFor(model => model.FirstName) %>
<%: Html.ValidationMessageFor(model => model.FirstName) %>
</div>
<div class="editor-label">
Last Name
</div>
<div class="editor-field">
<%: Html.TextBoxFor(model => model.LastName) %>
<%: Html.ValidationMessageFor(model => model.LastName) %>
</div>
<div class="editor-label">
Photo
</div>
<div class="editor-field">
<input id="Photo" name="Photo" type="file" />
</div>
<p>
<%: Html.Hidden("DeveloperID") %>
<%: Html.Hidden("CreateDate") %>
<input type="submit" value="Save" />
</p>
</fieldset>
<% } %>
And the controller:
//POST: /Secure/Developers/Save/
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Save(Developer developer)
{
//get profile photo.
var upload = Request.Files["Photo"];
if (upload.ContentLength > 0)
{
string savedFileName = Path.Combine(
ConfigurationManager.AppSettings["FileUploadDirectory"],
"Developer_" + developer.FirstName + "_" + developer.LastName + ".jpg");
upload.SaveAs(savedFileName);
}
developer.UpdateDate = DateTime.Now;
if (developer.DeveloperID == 0)
{//inserting new developer.
DataContext.DeveloperData.Insert(developer);
}
else
{//attaching existing developer.
DataContext.DeveloperData.Attach(developer);
}
//save changes.
DataContext.SaveChanges();
//redirect to developer list.
return RedirectToAction("Index");
}
Thanks,
Justin
