C# WPF "private" Anonymous Type member

using (var streamWriter = new StreamWriter(SomeRequest.GetRequestStream()))
{
    string json = JsonConvert.SerializeObject(new
    {
        Type_member1 = "StacOverFlow",
        Type_member2 = sometext,
        Type_member3 = 0,
        private = true
    });
    streamWriter.Write(json);
}

As you can see, there is Type member called "private". Of course, when i typed it, a message will pop-up and tell me:

"Invalid expression term 'private'"

Putting "private" inside quote will return this error:

"Invalid anonymous type member declarator. bla bla bla..."

Is there a way to solve this?

private is a reserved keyword of C# framework and can not it used as identifier in program. If you try to write string private = "sometext"; then compiler will throw exception by own stating Identifier 'private' is a keyword. So you should define the prop name as @private

Or you should inform serialize to name it as private at time of serialization.

This can be solved by using the syntax:

@private = true,

Note the use of @private (where the @ changes how the compiler interprets the source code); and changing the ; to a , to avoid the other syntax error.

Keywords [ie. private] are predefined, reserved identifiers that have special meanings to the compiler. They cannot be used as identifiers in your program unless they include @ as a prefix. For example, @if [ie. @private] is a valid identifier but if [ie. private] is not because if is a keyword.

Alternative, create a non-anonymous type (with a better code-friendly member name) and apply a [JsonProperty] or [DataMember] attribute to change the serialized name to 'private'.
