Assembly: Cuemon.Extensions.Core.dll

Extension methods for the MethodDescriptor class.

Inheritance: object

MethodDescriptorExtensions

Examples

MethodDescriptorExtensions provides extension methods for MethodDescriptor to inspect parameter information and method metadata. This example retrieves MethodInfo for Console.WriteLine(string) (which has a parameter) and Guid.NewGuid() (which has none), creates MethodDescriptor instances via MethodDescriptor.Create, then calls HasParameters() to check each for parameters. Key steps include resolving the method info via reflection and calling HasParameters on each descriptor. Console output confirms True for WriteLine, False for NewGuid, and displays the method name and caller name.

{
    public static void Demonstrate()
    {
        MethodInfo writeLine = typeof(Console).GetMethod(nameof(Console.WriteLine), new[] { typeof(string) });
        MethodInfo newGuid = typeof(Guid).GetMethod(nameof(Guid.NewGuid), BindingFlags.Public | BindingFlags.Static);

        MethodDescriptor withParameters = MethodDescriptor.Create(writeLine);
        MethodDescriptor withoutParameters = MethodDescriptor.Create(newGuid);

        Console.WriteLine(withParameters.HasParameters());
        Console.WriteLine(withoutParameters.HasParameters());
        Console.WriteLine(withParameters.Method.Name);
        Console.WriteLine(withParameters.Caller?.Name);
    }
}
