System.Windows.Forms.BindingSource.IndexOf Method

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

Syntax

public virtual int IndexOf (object value)

Parameters

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

Returns

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

Remarks

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

  • The BindingSource.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 BindingSource.Count property.

  • The underlying method determines equality by calling the object.Equals(object) method.
