c# - 二进制格式器到字符串

Question

    BinaryFormatter formatter = new BinaryFormatter();

    using (MemoryStream m = new MemoryStream())
    {
        formatter.Serialize(m, list);
        StreamReader sr = new StreamReader(m);
        HiddenField1.Value = sr.ReadToEnd();
    }

我得到 HiddenField1.Value 的空白值。不确定我在做什么甚至可能吗？列表肯定已填充 (is a List<T>)

取决于您想要实现的目标...一种选择是将二进制流的内容显示为 Base64 字符串:

var memoryStream = new MemoryStream();
using(memoryStream)
{
    formatter.Serialize(memoryStream, list);
}
HiddenField1.Value = Convert.ToBase64String(memoryStream.ToArray());
