• Declared in: RT.Util.ExtensionMethods.ArrayExtensions

Declaration

public static int IndexOfSubarray<T>(
    this T[] sourceArray,
    T[] findWhat,
    int startIndex,
    int? sourceLength = null,
    IEqualityComparer<T> comparer = null
)

Summary

Searches the current array for a specified subarray and returns the index of the first occurrence, or -1 if not found.

Generic type parameters

T	This type parameter is not documented.

Parameters

this T[]	sourceArray	Array in which to search for the subarray.
T[]	findWhat	Subarray to search for.
int	startIndex	Index in sourceArray at which to start searching.
int?	sourceLength	Maximum length of the source array to search starting from startIndex. The greatest index that can be returned is this minus the length of findWhat plus startIndex.
