I need to ignore empty strings from an Azure Function written in C#-CodePudding

I have managed to ignore the null buts but I have not been able to do the same with the empty strings. My project is an Azure Function running on .NET Core 3.1.

The configuration I have is the following in the startup

using Newtonsoft.Json;
using Newtonsoft.Json.Serialization;
using System.Text.Json.Serialization;


builder.Services.AddMvcCore()
            .AddNewtonsoftJson(options =>
            {
                options.UseMemberCasing();
                options.SerializerSettings.ContractResolver = new DefaultContractResolver();
                options.SerializerSettings.MetadataPropertyHandling = MetadataPropertyHandling.Ignore;
                options.SerializerSettings.Formatting = Formatting.Indented;
                options.SerializerSettings.DefaultValueHandling = DefaultValueHandling.Ignore;
                options.SerializerSettings.NullValueHandling = NullValueHandling.Ignore;
            })
            .AddJsonOptions(option =>
            {
                option.JsonSerializerOptions.IgnoreNullValues = true;
                option.JsonSerializerOptions.WriteIndented = true;
                option.JsonSerializerOptions.IgnoreReadOnlyProperties = true;
            });

Any idea why I don't ignore empty strings?

CodePudding user response：

Your settings seems to be correct. However you might need to decorate your properties with the Default value attribute for

CodePudding user response：

Maybe override the tostring method and pass in your JSON options there or just do some isnullorempty checks before you jsonStringify


override public string ToString() {
    return [Your format logic here];
}
