Why is this an issue?
When a loop is filtering, selecting or aggregating, those functions can be handled with a clearer, more concise LINQ expression instead.
Noncompliant code example
var result = new List<string>();
foreach (var element in collection) // Noncompliant
{
if (condition(element))
{
result.Add(element);
}
}
foreach (var element in collection2) // Noncompliant
{
var someValue = element.Property;
if (someValue != null)
{
result.Add(someValue);
}
}
Compliant solution
var result = new List<string>();
foreach (var element in collection.Where(x => condition(x)))
{
result.Add(element);
}
foreach (var someValue in collection2.Select(x => x.Property).Where(y => y != null))
{
result.Add(someValue);
}
