AL0045 - Use null-or-empty guard helper

Use Guard.NotNullOrEmpty() instead of verbose if (string.IsNullOrEmpty(…)) throw patterns

Source: Al0045UseGuardNotNullOrEmptyAnalyzer.cs

Description

Use Guard.NotNullOrEmpty() instead of verbose null-or-empty check and throw patterns. The guard helper is more concise and consistent.

Bad Code

public void Process(string name)
{
    if (string.IsNullOrEmpty(name))
        throw new ArgumentException("Cannot be null or empty", nameof(name));
}

Good Code

public void Process(string name)
{
    Guard.NotNullOrEmpty(name);
}
