SEC0012: String can be compared with .IsBeforeOrEqualTo()

Cause

The code contains an expression like string.Compare(a, b, comparison) <= 0

Rule description

Replace string.Compare(a, b, comparison) <= 0 with a.IsBeforeOrEqualTo(b, comparison)

How to fix violations

1. Add a using declaration for the Stravaig.Extensions.Core namespace if it does not already exist.
2. Replace any instance of string.Compare(a, b, comparison) <= 0 with a.IsBeforeOrEqualTo(b, comparison)

When to suppress warnings

If you prefer the original style of string check.

Example of a violation

if (string.Compare(a, b, StringComparison.OrdinalIgnoreCase) <= 0)
{
    // Perform work required when a is before or equal to b.
}
