String.Compare can be used

• Jun 26, 2019

CodeRush Classic shows the String.Compare can be used code issue if the == operator is used to compare two string values.

Fix

Use a String.Compare() call instead of the == operator.

Purpose

Highlights the string comparison expressions, which should be replaced with a String.Compare() call to improve code readability and provide additional comparison options.

Example

C#

private string _Text;
public bool ChangeText(string text)
{
    if (_Text == text)
        return false;
    _Text = text;
    return true;
}

Fix:

C#

private string _Text;
public bool ChangeText(string text)
{
    if (String.Compare(_Text, text, false) == 0)
        return false;
    _Text = text;
    return true;
}
