Public Function IndexOf (span As ReadOnlySpan(Of Char), value As ReadOnlySpan(Of Char), comparisonType As StringComparison) As IntegerParameters
- 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 span and value are compared.
Returns
The index of the occurrence of the value in the span.
Applies to
IndexOf<T>(Span<T>, T)
Searches for the specified value and returns the index of its first occurrence.

Public Function IndexOf(Of T As IEquatable(Of T)) (span As Span(Of T), value As T) As IntegerType Parameters
- T
The type of the span and value.
Parameters
- span
- Span<T>
The span to search.
- value
- T
The value to search for.
Returns
The index of the occurrence of the value in the span. If not found, returns -1.
Remarks
Values are compared using IEquatable{T}.Equals(T).
Applies to
IndexOf<T>(Span<T>, ReadOnlySpan<T>)
Searches for the specified sequence and returns the index of its first occurrence.

Parameters
- span
- Span<T>
The span to search.
- value
- ReadOnlySpan<T>
The sequence to search for.
Returns
The index of the occurrence of the value in the span. If not found, returns -1.
