ExpansionFunction.GetCurrentValue Method

Definition

Gets the current value of the expansion function.

Overloads

GetCurrentValue()

Gets the current value of the expansion function as a string.

GetCurrentValue(String, Int32)

Gets the current value of the expansion function.

Remarks

Determines the value of the expansion function by evaluating the arguments and returning an appropriate value.

GetCurrentValue()

Gets the current value of the expansion function as a string.

public:
 abstract System::String ^ GetCurrentValue();
public:
 abstract Platform::String ^ GetCurrentValue();
 abstract std::wstring GetCurrentValue();
public abstract string GetCurrentValue ();
abstract member GetCurrentValue : unit -> string
Public MustOverride Function GetCurrentValue () As String

Returns

The current value of the expansion function, otherwise null.

Remarks

You must implement this method in a class derived from the ExpansionFunction class in order to provide a value for an expansion function. Your implementation of this method can call the GetArgument method to obtain values for any arguments the expansion function may have. Returning a null value indicates that the expansion function could not be evaluated (in which case the default value of the field is shown).
