C# importing class as *

After building my first big project using C# i ran into a problem. My project file is about 7000 lines big atm and fillde with functions and other classes. This is ofcourse a little messy and to find the code that i actually need i sometimes need to scroll around quite a bit so i want to remove all the classes and functions to a different file. I know i can just add a c# class file and then access it by doing

    namespace Namespace
{
    class Functions
    {
        // Example Functions here
    }
}

    namespace OtherNamespace
{
    class OtherClass
    {
        Namespace.Functions.Examplefunction
    }
}

If the example function would actually exist that is. But i would like to get rid of the Namespace.Functions part as it would save me alot of typing and i use these functions often. How would i do that ? Is it even possible?

I know it is achievable in python like this

import math as *

for example, then you wouldnt have to write

math.cos(0)

but instead you can just write

cos(0)

You can use a static import feature of C# if you want to use many static helper functions. I've provided a basic example. You can use this for standard .NET framework classes such as System.Math, System.Console etc.

namespace Utils 
{
    // using static
    using static Utils.Helper;

    public class Program
    {
        public static void Main()
        {
            // no need to type Helper.Pow(2, 2);
            var x = Pow(2, 2);

            Console.WriteLine(x);
        }
    }
}

namespace Utils
{
    public static class Helper
    {
        public static double Pow(int x, int pow) => Math.Pow(x, pow);
    }
}
