== Noncompliant Code Example

----
public void Sample(bool b, bool c, string s)
{
    var a = true;
    if (a) // Noncompliant
    {
        DoSomething();
    }

    if (b && a) // Noncompliant; "a" is always "true"
    {
        DoSomething();
    }

    if (c || !a) // Noncompliant; "!a" is always "false"
    {
        DoSomething();
    }

    string d = null;
    var v1 = d ?? "value"; // Noncompliant, d is always null
    var v2 = s ?? d; // Noncompliant, d is always null and the produced value is always equal to s. The condition to check the value of s is gratuitous.
}

== Compliant Solution

----
public void Sample(bool b, bool c, string s)
{
    var a = true;
    if (Foo(a))
    {
        DoSomething();
    }

    if (b)
    {
        DoSomething();
    }

    if (c)
    {
        DoSomething();
    }

    var v1 = "value";
    var v2 = s;
}
