BindingSource.IndexOf Method

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

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

public virtual int IndexOf (
	Object value
)
public int IndexOf (
	Object value
)
public function IndexOf (
	value : Object
) : int
Not applicable.

Parameters

value

The Object to locate in the underlying list represented by the List property. The value can be a null reference (Nothing in Visual Basic).

Return Value

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.
