Question 86162 in ASP.NET Question posted in
The official documentation can be found here.

In .NET 7 Web API the first character of item is automatically becomes lower case – Asp.net

I have a web service with .NET 7. When I get the data from the database and send it as JSON, the first letter of the class items is sent in lowercase.

In order to explain the problem, I wrote a test web service

testClass.cs

    public class testClass
    {
        public String Date1 { get; set; }
        public String Date2 { get; set; }

        public testClass(string date1, string date2)
        {
            Date1 = date1;
            Date2 = date2;
        }
    }

and my api:

    [HttpGet(Name = "test")]
    public testClass Get()
    {
        return (new testClass("d1", "d2"));

    }

the result is:

{
  "date1": "d1",
  "date2": "d2"
}

But I want the result to be as follows:

{
  "Date1": "d1",
  "Date2": "d2"
}

    Default mode for JsonSerializerOptions is camel-casing (The first word starts with a small letter and capital letter appears at the start of the second word and at each new subsequent word that follows it).

    You can get more information in this link:
    JsonSerializerOptions.PropertyNamingPolicy

    You just need to add the following configuration to Program.cs:

    builder.Services.AddControllers()
        .AddJsonOptions(options =>
        {
             options.JsonSerializerOptions.PropertyNamingPolicy = null;
        });

    Or just add JsonProperty:

    public class testClass
{
    [JsonProperty("Date1")]
    public String Date1 { get; set; }

    [JsonProperty("Date2")]
    public String Date2 { get; set; }

    public testClass(string date1, string date2)
    {
        Date1 = date1;
        Date2 = date2;
    }
}
