C# 校验Json格式

错误json：错误值 -2146.379

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：
