System.Windows.Forms.BindingSource.Contains Method

Determines whether an object is an item in the list.

Syntax

public virtual bool Contains (object value)

Parameters

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

Returns

true if the value parameter is found in the BindingSource.List; otherwise, false.

Remarks

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

  • 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.
