Member can be static

CodeRush Classic shows the Member can be static code issue if a member of a non-static class does not include calls to non-static members of this class.

Fix

Add the static keyword to the member declaration.

Purpose

Highlights the members, which can be made static to increase the scope at which they can be called.

Example

public class MyClass
{
    public int[] Numbers { get; set; }
    public int GetMaxValue()
    {
        int result = int.MinValue;
        foreach (int num in Numbers)
            result = GetGreaterValue(num, result);
        return result;
    }
    public int GetGreaterValue(int value1, int value2)
    {
        if (value1>value2)
            return value1;
        return value2;
    }
}

Fix:

public class MyClass
{
    public int[] Numbers { get; set; }
    public int GetMaxValue()
    {
        int result = int.MinValue;
        foreach (int num in Numbers)
            result = GetGreaterValue(num, result);
        return result;
    }
    public static int GetGreaterValue(int value1, int value2)
    {
        if (value1>value2)
            return value1;
        return value2;
    }
}
