通过表单POST发送base64数据图像

I have two images in the form of (somewhat):

我有两张(有点)的图片:

<img src="data: base64, OIJQWEFOIJQWEFOIJQWEF..." />
<img src="data: base64, OIJQWEFOIJQWEFOIJQWEF..." />

I have no choice in the matter, these images are always going to be set as base64 data.

我在这个问题上没有选择，这些图像总是被设置为base64数据。

If I were to POST these using some client side magic, how can I convert the strings to actual images?

如果我使用客户端魔法发布这些，我如何将字符串转换成实际的图像?

public ActionResult Combine(string imageA, string imageB)
{
    // imageA and imageB would be the strings.
    return View();
}

Use Convert.FromBase64String method.
This method:

使用转换。FromBase64String方法。这个方法:

Converts the specified string, which encodes binary data as base-64 digits, to an equivalent 8-bit unsigned integer array.

将指定的字符串(将二进制数据编码为base-64位数字)转换为等效的8位无符号整数数组。

Then you can use WebImage class from System.Web.Helpers.dll assembly to convert byte array to actual image and perform some manipulations on it.

然后可以使用system . web . helper类中的WebImage类。将字节数组转换为实际图像并对其执行一些操作的dll程序集。
