AutomationElement.ProcessIdProperty 欄位


識別 ProcessId 屬性。Identifies the ProcessId property.

public: static initonly System::Windows::Automation::AutomationProperty ^ ProcessIdProperty;
public static readonly System.Windows.Automation.AutomationProperty ProcessIdProperty;
 staticval mutable ProcessIdProperty : System.Windows.Automation.AutomationProperty
Public Shared ReadOnly ProcessIdProperty As AutomationProperty 




下列範例會抓取屬性的目前值。The following example retrieves the current value of the property. 如果元素未提供預設值,則會傳回預設值。The default value is returned if the element does not provide one.

int processIdentifier = (int)
Dim processIdentifier As Integer = _

下列範例會抓取屬性目前的值,但指定如果專案本身未提供屬性的值, NotSupported 則會傳回而不是預設值。The following example retrieves the current value of the property, but specifies that if the element itself does not provide a value for the property, NotSupported is to be returned instead of a default value.

int processIdentifier1;
object processIdentifierNoDefault =
    autoElement.GetCurrentPropertyValue(AutomationElement.ProcessIdProperty, true);
if (processIdentifierNoDefault == AutomationElement.NotSupported)
    // TODO Handle the case where you do not wish to proceed using the default value.
    processIdentifier1 = (int)processIdentifierNoDefault;
Dim processIdentifier1 As Integer
Dim processIdentifierNoDefault As Object = autoElement.GetCurrentPropertyValue(AutomationElement.ProcessIdProperty, True)
If processIdentifierNoDefault Is AutomationElement.NotSupported Then
    ' TODO Handle the case where you do not wish to proceed using the default value.
    processIdentifier1 = CInt(processIdentifierNoDefault)
End If


消費者介面自動化用戶端應用程式會使用此識別碼。This identifier is used by UI Automation client applications. 消費者介面自動化提供者應該在中使用對等的識別碼 AutomationElementIdentifiersUI Automation providers should use the equivalent identifier in AutomationElementIdentifiers.

這個屬性也可以從 Current 或屬性中抓取 CachedThis property can also be retrieved from the Current or Cached properties.

屬性的傳回值屬於類型 Int32Return values of the property are of type Int32. 屬性的預設值為 0。The default value for the property is 0.
