C# 校验Json格式

错误json：错误值 -2146.379

[{"Key": "surface_heights_average","Value": "-2122.739nm","Description": "surface_heights_average"}, {"Key": "surface_heights_max","Value": "-2105.69nm","Description": "surface_heights_max"}, {"Key": "surface_heights_min","Value": "-2146.165nm","Description": "surface_heights_min"}, {"Key": "hole_heights_average","Value": "-2092.042nm","Description": "hole_heights_average"}, {"Key": "hole_heights_max","Value": "-2075.576nm","Description": "hole_heights_max"}, -2146.379, {"Key": "hole_depths_average","Value": "-30.697nm","Description": "hole_depths_average"}
]

发现 Newtonsoft.Json 不能正常校验出json异常，除非反序列化到具体的实体类，使用Json Schema 可以正常校验异常位置

一、Newtonsoft.Json 反序列化校验

public bool IsValidJson(string jsonString)
{try{var obj = JsonConvert.DeserializeObject(jsonString);//var obj = JObject.Parse(jsonString);return true;}catch (JsonReaderException){return false;}
}

不能正确校验异常

二、Json Schema 校验

nuget包：NJsonSchema

string json = @"[{""Key"": ""surface_heights_average"",""Value"": ""-2122.739nm"",""Description"": ""surface_heights_average""}, {""Key"": ""surface_heights_max"",""Value"": ""-2105.69nm"",""Description"": ""surface_heights_max""}, {""Key"": ""surface_heights_min"",""Value"": ""-2146.165nm"",""Description"": ""surface_heights_min""}, {""Key"": ""hole_heights_average"",""Value"": ""-2092.042nm"",""Description"": ""hole_heights_average""}, {""Key"": ""hole_heights_max"",""Value"": ""-2075.576nm"",""Description"": ""hole_heights_max""}, -2146.379, {""Key"": ""hole_depths_average"",""Value"": ""-30.697nm"",""Description"": ""hole_depths_average""}
]
";
var schema =  JsonSchema.FromSampleJson(json);
var errors = schema.Validate(json);foreach (var error in errors)Console.WriteLine($"json异常: 行号：{error.LineNumber} 位置：{error.LinePosition}");

output：
