Extensions.IsNullOrEmpty
Small set of C# extension methods to check for null/empty/zero across common types.
Install
Use the .NET CLI:
dotnet add package Kebechet.Extensions.IsNullOrEmpty
Usage
using System;
using System.Collections.Generic;
using IsNullOrEmpty.Extensions;
// Strings
string? s1 = null;
bool a = s1.IsNullOrEmpty(); // true
string? s2 = " ";
bool b = s2.IsNullOrWhiteSpace(); // true
// Collections
IEnumerable<int>? numbers = null;
bool c = numbers.IsNullOrEmpty(); // true
var list = new List<string>();
bool d = list.IsNullOrEmpty(); // true when empty
// Guid
Guid? id1 = null;
bool e = id1.IsNullOrEmpty(); // true
Guid? id2 = Guid.Empty;
bool f = id2.IsNullOrEmpty(); // true
// Numerics (nullable)
int? i = 0;
long? l = null;
double? dbl = 0.0;
decimal? dec = 5m;
float? fl = 0f;
bool g = i.IsNullOrZero(); // true
bool h = l.IsNullOrZero(); // true
bool j = dbl.IsNullOrZero(); // true
bool k = dec.IsNullOrZero(); // false
bool m = fl.IsNullOrZero(); // true
Nullable flow analysis
All methods are annotated with [NotNullWhen(false)], so Roslyn's nullable analysis understands the null check:
string? name = GetName();
if (name.IsNullOrEmpty())
{
return;
}
// No nullable warning here — Roslyn knows name is not null
Console.WriteLine(name.Length);
