BindingSource.IndexOf(Object) BindingSource.IndexOf(Object) BindingSource.IndexOf(Object) BindingSource.IndexOf(Object) Method


Searches for the specified object and returns the index of the first occurrence within the entire list.

 virtual int IndexOf(System::Object ^ value);
public virtual int IndexOf (object value);
abstract member IndexOf : obj -> int
override this.IndexOf : obj -> int
Public Overridable Function IndexOf (value As Object) As Integer


Object Object Object Object

The Object to locate in the underlying list represented by the List property. The value can be null.


The zero-based index of the first occurrence of the value parameter; otherwise, -1 if value is not in the list.



Although the implementation is dependent on the underlying list's IndexOf method, typically the following characteristics apply:

  • The List is searched starting at the first element and ending at the last element.

  • The underlying method performs a linear search; therefore, the average execution time is proportional to the value of the Count property.

  • The underlying method determines equality by calling the Equals method.
