base64编码的字符串转化成二进制流和照片

Question

现有一strBase64PhotoData: WideString返回值参数，是照片的二进制数据转成的base64字符转，如何转换回去变成照片啊？为方便测试，把这个base64字符串贴出来，请大家测试可以生成照片，谢谢。另外请指点照片再转成base64字符转怎么转变啊，就是来回的转换代码求大神指点，谢谢。

Answer 1

直接Base64Decode回去成二进制数组，然后看图片需要什么样的数据源，转换后赋给它，仅给个思路参考

Answer 2

//将base64转化为图片文件
//将Base64字符串转化为byte数组--------------------------------------------------
class function TImgOper.BaseStrToByte(BaseStr: string): string;

  try
    Ms := TMemoryStream.Create;

      Ss := TStringStream.Create(BaseStr);
      try
        DecodeStr := DecodeFile.Create;
        try

  except on e:exception do

  end;
