推荐答案

第 1 步是将 base64 字符串转换为字节数组:

Step 1 is converting from your base64 string to a byte array:

byte[] bytes = Convert.FromBase64String(base64BinaryStr);

第 2 步是将字节数组保存到磁盘:

Step 2 is saving the byte array to disk:

System.IO.FileStream stream = 
    new FileStream(@"C:file.pdf", FileMode.CreateNew);
System.IO.BinaryWriter writer = 
    new BinaryWriter(stream);
writer.Write(bytes, 0, bytes.Length);
writer.Close();
