[大数据]C# 如何快速去除UTF8.Bom暨Newtonsoft.Json.JsonConvert.DeserializeObject.JsonReaderException解决方案

using System.Text;

class TextEncoding
{
    public readonly static Encoding Utf8 = Encoding.UTF8;
    public readonly static Encoding Utf8Bom = new UTF8Encoding(true);
    public readonly static Encoding Utf8NoBom = new UTF8Encoding(false);
    public readonly static byte[] Utf8BomBytes = { 0xEF, 0xBB, 0xBF };

    public static bool HasBom(byte[] bytes)
    => bytes[0] == Utf8BomBytes[0] && bytes[1] == Utf8BomBytes[1] && bytes[2] == Utf8BomBytes[2];

    public static string GetUtf8RemovedBomString(byte[] bytes)
    {
        if (HasBom(bytes))
            return Utf8.GetString(bytes, 3, bytes.Length - 3);
        return Utf8.GetString(bytes);
    }
}
