G-Research F# Analyzers
StringAnalyzer
There are multiple analyzers for various string comparison functions:
- String.EndsWith Analyzer
- String.StartsWith Analyzer
- String.IndexOf Analyzer
Problem
The recommendations for string usage mention calling the overloads using StringComparison to increase performance.
"foo".EndsWith("p")
Fix
Signal your intention explicitly by calling an overload.
open System
"foo".EndsWith("p", StringComparison.Ordinal)
namespace System
[<Struct>]
type StringComparison =
| CurrentCulture = 0
| CurrentCultureIgnoreCase = 1
| InvariantCulture = 2
| InvariantCultureIgnoreCase = 3
| Ordinal = 4
| OrdinalIgnoreCase = 5
