我正在处理以下回复:
{"id":"https://login.salesforce.com/id/00Dx0000000BV7z/005x00000012Q9P",
"issued_at":"1278448832702","instance_url":"https://na1.salesforce.com",
"signature":"0CmxinZir53Yex7nE0TD+zMpvIWYGb/bdJh6XfOH6EQ=","access_token":
"00Dx0000000BV7z!AR8AQAxo9UfVkh8AlV0Gomt9Czx9LjHnSSpwBMmbRcgKFmxOtvxjTrKW1
9ye6PE3Ds1eQz3z8jr3W7_VbWmEu4Q8TVGSTHxs"}
我正在尝试将其反序列化为类似于以下的类:
public class TokenResponse {
public string Id { get; set; }
[JsonProperty(PropertyName = "issued_at")]
public DateTime IssuedAt { get; set; }
public string Signature { get; set; }
[JsonProperty(PropertyName = "instance_url")]
public string InstanceUrl { get; set; }
[JsonProperty(PropertyName = "access_token")]
public string AccessToken { get; set; }
}
反序列化的调用非常简单:
JsonConvert.DeserializeObject<TokenResponse>(response.Content);
这会导致异常:
Could not convert string to DateTime: 1278448832702.
有没有办法让JSON.NET正确地反序列化这个日期?

您可以创建自定义DateTime转换器
var token = JsonConvert.DeserializeObject<TokenResponse>(response.Content,
new MyDateTimeConverter());
public class MyDateTimeConverter : Newtonsoft.Json.JsonConverter
{
public override bool CanConvert(Type objectType)
{
return objectType == typeof(DateTime);
}
public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
var t = long.Parse((string)reader.Value);
return new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc).AddMilliseconds(t);
}
public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
{
throw new NotImplementedException();
}
}
