| Contains(ReadOnlySpan<Char>, ReadOnlySpan<Char>, StringComparison) |
Indicates whether a specified value occurs within a read-only character span. |
| Contains<T>(ReadOnlySpan<T>, T) |
Indicates whether a specified value is found in a read-only span. Values are compared using IEquatable{T}.Equals(T). |
| Contains<T>(Span<T>, T) |
Indicates whether a specified value is found in a span. Values are compared using IEquatable{T}.Equals(T). |
| Contains<T>(ReadOnlySpan<T>, T, IEqualityComparer<T>) |
Indicates whether a specified value occurs within a read-only character span.

Public Function Contains (span As ReadOnlySpan(Of Char), value As ReadOnlySpan(Of Char), comparisonType As StringComparison) As BooleanParameters
- span
- ReadOnlySpan<Char>
The source span.
- value
- ReadOnlySpan<Char>
The value to seek within the source span.
- comparisonType
- StringComparison
An enumeration value that determines how the characters in span and value are compared.
Returns
true if value occurs within the span, false otherwise.
