delphi 与 c# 转 base64 结果不同

Posted 2023-04-16

var parambts = Encoding.UTF8.GetBytes(this.richTextBox1.Text);
var base64Param = Convert.ToBase64String(parambts);
richTextBox4.Text = base64Param;
转 - delphi xe5 语音 ？？？
求 C# 转 - delphi xe5 语语言 ？？？

我也遇到这个问题。现在解决了，是base64的encode的问题：
public static string DecodeBase64(string code, string encodeName)

string decode = "";
byte[] bytes = Convert.FromBase64String(code);
try

decode = Encoding.GetEncoding(encodeName).GetString(bytes);

catch

decode = code;

return decode;


string s2 = DecodeBase64(base编码的内容, "GB2312"); 参考技术A 用base64_decode();试试能不能解码.很可能对方用是base64进行编码的.追问

base64_decode() 这个函数 是 delphi xe5 的么 ？

C# Image与Base64编码互转函数

public Bitmap GetImageFromBase64(string base64string)
        {
            byte[] b = Convert.FromBase64String(base64string);
            MemoryStream ms = new MemoryStream(b);
            Bitmap bitmap = new Bitmap(ms);
            return bitmap;
        }
public string GetBase64FromImage(string imagefile)
{
    string strbaser64 = "";
    try
    {
        Bitmap bmp = new Bitmap(imagefile);              
        MemoryStream ms = new MemoryStream();
        bmp.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
        byte[] arr = new byte[ms.Length];
        ms.Position = 0;
        ms.Read(arr, 0, (int)ms.Length);
        ms.Close();
        strbaser64 = Convert.ToBase64String(arr);
    }
    catch (Exception)
    {
        throw new Exception("Something wrong during convert!");
    }
    return strbaser64;
}
