C# (CSharp) Nullable.Any示例

示例#1

        public void AnyWithPredicate()
        {
            Nullable <int> n  = 2;
            Nullable <int> n0 = null;

            Assert.Throws <ArgumentNullException>(() => NullableExtensions.Any <int>(n, null));

            Assert.True(n.Any(i => i == 2));
            Assert.False(n.Any(i => i == 3));
            Assert.False(n0.Any(i => i == 2));
            Assert.False(n0.Any(i => i == 3));
        }

示例#2

        public void Any()
        {
            Nullable <int> n  = 2;
            Nullable <int> n0 = null;

            Assert.True(n.Any());
            Assert.False(n0.Any());
        }
