解码 base64 图像

Question

我想将 base64 字符串解码为图像。 我正在使用以下代码进行解码，

string base64string = subSocket.ReceiveFrameString();
       
if (base64string.Length > 1000)
{
    var base64Data = Regex.Match(base64string, @"data:image/(?<type>.+?),(?<data>.+)").Groups["data"].Value;
    byte[] imgBytes  = Convert.FromBase64String(base64Data);
    myTexture.LoadRawTextureData(imgBytes);
    myTexture.Apply();

    rawImg.texture = myTexture;
}

不幸的是，它抛出了 FormatException。 如何正确解码 base64 图像。 以下是我的 base64 字符串。

Answer 1

由于不可能,在 base64 字符串中，它也是分隔符，所以图像部分就在逗号后面：

byte[] imgBytes  = Convert.FromBase64String(base64string.Split(',')[1]);
