推荐答案

您需要用JavaScript来验证，这里是一个样本

You will need to validate with javascript, here is a sample

function onSelect(e) {
    if (e.files[0].size > 256000) {
        alert('The file size is too large for upload');
        e.preventDefault();
        return false;
    }
    // Array with information about the uploaded files
    var files = e.files;
    var ext = $('#logo').val().split('.').pop().toLowerCase();
    if ($.inArray(ext, ['gif', 'jpeg', 'jpg', 'png', 'tif', 'pdf']) == -1) {
        alert('This type of file is restricted from being uploaded due to security reasons');
        e.preventDefault();
        return false;
    } 
    return true;
}

这表示，文件大小不得超过256K更大，只允许GIF，JPG，JPEG，TIF，PNG和PDF。只要改变为256000 5000000，您的特定文件类型

this says the file must be no greater than 256K and allows only gif, jpg, jpeg, tif, png and pdf. Just change 256000 to 5000000 and your specific file type

我在MVC 3与Telerik的上传控件剃刀视图用这个。你可以用一个标准上传输入使用，以及，刚刚火上选择或之前提交此事件

I'm using this in MVC 3 in a razor view with the Telerik upload control. You can use with a standard upload input as well, just fire this event on selection or before committing
