ClickAsync() Clicks the element. Dispose() Disposes the ElementHandle. Equals(object obj) Determines whether the specified object is equal to the current object. (Inherited from Object) Finalize() Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) GetHashCode() Serves as the default hash function. (Inherited from Object) GetPropertyAsync(string propertyName) Returns the property value of the element. GetPropertyAsync(string propertyName, object[] args) Returns the property value of the element. GetPropertiesAsync() Returns the properties of the element. GetBoundingBoxAsync() Returns the bounding box of the element. GetElementAsync(string selector) Returns the first element that matches the specified selector. GetElementsAsync(string selector) Returns the first element that matches the specified selector. Get
