Assembly: Microsoft.Office.Interop.UccApi (in microsoft.office.interop.uccapi.dll)

UccProperty get_NamedProperty (
	string bstrPropertyId
UccProperty get_NamedProperty (
	String bstrPropertyId
function get_NamedProperty (
	bstrPropertyId : String
) : UccProperty



A value of the BSTR (string, for a .NET application) type. This specifies the name of a property.

Return Value

A value of the IUccProperty** (IUccProperty, for a .NET application) type. This returns an instance of the property of the given name.

A named property uses a string as the property ID. Attempting to get a property out of a read-only property collection where that property has not been set in the collection yields a COM error. Before attempting to access a property, the existence of the property should be verified. Calling into IsNamedPropertySet and passing the string Id of interest returns a boolean value. A true value indicates the property has been set and can be retrieved.

Win32 COM/C++ Syntax

HRESULT get_NamedProperty
   BSTR bstrPropertyId,
   IUccProperty** ppProperty
In a Win32 application, the return value of a method or property is always an HRESULT value indicating the status of the call to the interface member. Any result of the operation is returned as a parameter marked with the [out, retval] attribute. In contrast, in a .NET application the HRESULT value indicating an error condition is returned as a COM exception and the [out, retval] parameter becomes the return value. For the UCC API-defined HRESULT values, see Trace and Handle Errors in Unified Communications Client API.

The following example accepts a read-only property collection and a string representing the named property of interest. The existence of the named property is tested and if exists, the string value of the property is returned.

private string GetPropertyStringValue(
   IUccReadOnlyPropertyCollection pCollection, 
   string propertyName)
   //initialize return value
   string returnValue = string.Empty;
   IUccProperty property;

   //verify interested property was set
   if (pCollection.IsNamedPropertySet(propertyName))
      //get interested property and fill returnValue with string value of property
      property = pCollection.get_NamedProperty(propertyName);
      returnValue = property.StringValue;

   return returnValue;
