  Determines whether an element is in the System.Collections.Generic.List.

  Parameters

  • item: T | JsType<T>

    The object to locate in the System.Collections.Generic.List. The value can be null for reference types.

  Returns boolean

  true if item is found in the System.Collections.Generic.List; otherwise, false.

IndexOf

• IndexOf(item: T | JsType<T>): number

  Searches for the specified object and returns the zero-based index of the first occurrence within the entire System.Collections.Generic.List.

  Parameters

  • item: T | JsType<T>

    The object to locate in the System.Collections.Generic.List. The value can be null for reference types.

  Returns number

  The zero-based index of the first occurrence of item within the entire System.Collections.Generic.List, if found; otherwise, -1.

• IndexOf(item: T | JsType<T>, index: number | Int32): number

  Searches for the specified object and returns the zero-based index of the first occurrence within the range of elements in the System.Collections.Generic.List that extends from the specified index to the last element.

  Parameters

  • item: T | JsType<T>

    The object to locate in the System.Collections.Generic.List. The value can be null for reference types.

  • index: number | Int32

    The zero-based starting index of the search. 0 (zero) is valid in an empty list.

  Returns number

  The zero-based index of the first occurrence of item within the range of elements in the System.Collections.Generic.List that extends from index to the last element, if found; otherwise, -1.

Insert
