Method which is not valid in the given context. Need help

C#

Unity says "PlayerMovement.TakeInput()" is a method, which is not valid in the given context.
This is my code

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerMovement : MonoBehaviour
{
    public float speed;
    private Vector2 direction;

    void Update()
    {
        TakeInput();
        Move();
    }

    private void Move()
    {
        transform.Translate(direction * speed * Time.deltaTime);
    }

    private void TakeInput()
    {
        direction = Vector2.zero;
        if (TakeInput.GetKey(KeyCode.W))
        {
            direction += Vector2.up;

        }
        if (TakeInput.GetKey(KeyCode.A))
        {
            direction += Vector2.left;

        }
        if (TakeInput.GetKey(KeyCode.S))
        {
            direction += Vector2.down;

        }
        if (TakeInput.GetKey(KeyCode.D))
        {
            direction += Vector2.right;

        }
    }
}
