JsonStringEnumConverter没有对Enum的自定义JsonPropertyNameAttribute处理

[bunnyi116]

Description

问题相关类
System.Text.Json.JsonSerializer
System.Text.Json.Serialization.JsonStringEnumConverter

无法读取通过JsonStringEnumConverter转换器读取到枚举JsonPropertyNameAttribute特性属性名

Reproduction Steps

using System.Runtime.Serialization;
using System.Text.Json;
using System.Text.Json.Serialization;



Console.WriteLine(JsonSerializer.Serialize(new Test(), new JsonSerializerOptions() { WriteIndented = true })); ;


public class Test
{
    [JsonPropertyName("data1")]
    public DataType Days1 => DataType.TestData1;

    [JsonPropertyName("data2")]
    public DataType Days2 => DataType.TestData2;

    [JsonPropertyName("data3")]
    public DataType Days3 => DataType.TestData3;
}

[JsonConverter(typeof(JsonStringEnumConverter))]
public enum DataType
{
    [JsonPropertyName("testData1")]
    [EnumMember(Value = "testData1")]
    TestData1,

    [JsonPropertyName("testData2")]
    [EnumMember(Value = "testData2")]
    TestData2,

    TestData3,

};

Expected behavior

源 JSON 结果

{
  "data1": "TestData1",
  "data2": "TestData2",
  "data3": "TestData3"
}

预期 JSON 结果

{
  "data1": "testData1",
  "data2": "testData2",
  "data3": "TestData3"
}

Actual behavior

略...

Regression?

No response

Known Workarounds

添加对 JsonStringEnumConverter 的 JsonPropertyNameAttribute 的读取支持
