Undeclared element

• Apr 29, 2019

CodeRush Classic shows the Undeclared element code issue if the current code element is not declared.

Fix

Declare the code element.

Purpose

Highlights the code elements, which would cause the The name ‘Element name’ does not exist in the current context compilation error.

Example

C#

public class MyClass
{
    public void AddText(string text)
    {
        if (_Data == null)
            _Data = new List<string>();
        _Data.Add(text);
    }
}

Fix:

C#

public class MyClass
{
    private List<string> _Data = null;
    public void AddText(string text)
    {
        if (_Data == null)
            _Data = new List<string>();
        _Data.Add(text);
    }
}
