一次做到一个关于使用DataContractJsonSerializer类的表述。其中需要用到MemoryStream数组读取。发生数组溢出错误,这里特记录一笔:

public static class JsonSerializer<T> where T:new()
{
public static string Serialize(T obj)
{
string json = null;
using (MemoryStream ms = new MemoryStream())
{
try
{
DataContractJsonSerializer jsonS = new DataContractJsonSerializer(typeof(T));
jsonS.WriteObject(ms, obj);
ms.Position = ;
// 总的要读入的字节数数组
byte[] bytes = new byte[ms.Length];
// 读取数据的起始点
int offset = ; // 判断起始点+偏移量的数据必须在数组总的范围内
while (offset+<ms.Length)
{
// 尝试读取后10个数据
ms.Read(bytes, offset, );
// 起始点+10
offset += ;
} //剩余的数组全部读完
if (offset + >= ms.Length)
{
ms.Read(bytes, offset, (int)(ms.Length -
offset));
}
json = Encoding.UTF8.GetString(bytes);
}
catch (Exception ex)
{ }
}
return json;
} public static T Deserialize(string json)
{
T returnValue = default(T); using (MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(json)))
{
ms.Position = ;
DataContractJsonSerializer ds = new DataContractJsonSerializer(typeof(T));
returnValue = (T)ds.ReadObject(ms);
}
return returnValue;
}
}
