在 .net core 3.1 中使用 System.Text.Json 从文件加载后从 json 中删除空格

Question

I am using .NET Core 3.1 with System.Text.Json I am reading JSON from file

var jsonFilename = Path.Combine(Path.GetDirectoryName(Assembly.GetEntryAssembly().Location), "WellKnownConfig.json");
if (System.IO.File.Exists(jsonFilename))
{
    var fileContent = System.IO.File.ReadAllText(jsonFilename);
    if (!string.IsNullOrWhiteSpace(fileContent))
    {
         //var o = JsonDocument.Parse(fileContent);                        
         Result = new OkObjectResult(fileContent);
    }
    else
    {
        Result = new NoContentResult();
    }
}

The problem is it is having whitespaces. anyway, I can remove white spaces without string parsing. Like some way from System.Text.Json by loading into some object while using JsonDocument or JsonSerializer

Also is there some way I can minify this JSON after loading it from file

I have seen some solution for newtonjson

Following Did the trick. I hope it will help other's as well

 var fileContent = System.IO.File.ReadAllText(jsonFilename);
                    if (!string.IsNullOrWhiteSpace(fileContent) && Utility.IsValidJson(fileContent))
                    {
                        var obj = JsonSerializer.Deserialize<object>(fileContent);
                        Result = new OkObjectResult(obj);
                    }
                    else
                    {
                        Result = new NoContentResult();
                    }
