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
)

Parameters

value
Type: System.Object

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

Return Value

Type: System.Int32
The zero-based index of the first occurrence of the value parameter; otherwise, -1 if value is not in the list.

Implements

IList.IndexOf(Object)

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.
