In System.Text.Json is it possible to specify custom indentation rules in C#?

Yes, it is possible to specify custom indentation rules in System.Text.Json in C#.

The JsonSerializerOptions class provides several properties that control the formatting of the JSON output. To set custom indentation rules, you can set the JsonSerializerOptions.WriteIndented property to true, and then specify the string that should be used as the indentation string using the JsonSerializerOptions.Indent property.

For example, if you want to use four spaces as the indentation string, you can create a JsonSerializerOptions instance and set the WriteIndented and Indent properties as follows:

JsonSerializerOptions options = new JsonSerializerOptions
{
    WriteIndented = true,
    Indent = "    " // Use four spaces as the indentation string
};

You can then pass this options object to the JsonSerializer.Serialize method to serialize your object with the custom indentation rules:

string jsonString = JsonSerializer.Serialize(myObject, options);

This will produce a JSON string with each level of the JSON hierarchy indented with four spaces.
