To determine whether value exists in array, the method performs an equality comparison by calling each element's Equals method until it finds a match. This method searches all the elements of a one-dimensional array for value. ' The first occurrence of "the" between index 7 and index 11 is at index 10. ' The first occurrence of "the" between index 4 and the end is at index 6. ' The first occurrence of "the" is at index 0. ' The array contains the following values: ' The example displays the following output: SearchString, position, strings.GetUpperBound(0), index) Create a string array with 3 elements having the same value.Īrray^ strings =. IndexOf(Array, Object, Int32, Int32), to determine the first occurrence of the string "the" in a string array from the element that follows the last successful match to the end of the array. IndexOf(Array, Object, Int32), to determine the first occurrence of the string "the" in the fourth to the last elements of a string array. IndexOf(Array, Object), to determine the first occurrence of the string "the" in a string array. The example calls the following three overloads of the IndexOf method to find the index of a string in a string array: The range extends from a specified index for a specified number of elements. Searches for the specified object in a range of elements of a one-dimensional array, and returns the index of its first occurrence. The range extends from a specified index to the end of the array. Searches for the specified object in a range of elements of a one dimensional array, and returns the index of its first occurrence. Searches for the specified object in a range of elements of a one-dimensional array, and returns the index of ifs first occurrence. Searches for the specified object and returns the index of its first occurrence in a one-dimensional array. Searches for the specified object and returns the index of its first occurrence in a one-dimensional array or in a range of elements in the array.
