Sets the property value for the given object to the given value.

Overload List

Sets the value of the property with optional index values for index properties.

Supported by the .NET Compact Framework.

[Visual Basic] Overloads Public Overridable Sub SetValue(Object, Object, Object())

[C#] public virtual void SetValue(object, object, object[]);

[C++] public: virtual void SetValue(Object*, Object*, Object*[]);

[JScript] public function SetValue(Object, Object, Object[]);

When overridden in a derived class, sets the property value for the given object to the given value.

Supported by the .NET Compact Framework.

[Visual Basic] Overloads Public MustOverride Sub SetValue(Object, Object, BindingFlags, Binder, Object(), CultureInfo)

[C#] public abstract void SetValue(object, object, BindingFlags, Binder, object[], CultureInfo);

[C++] public: virtual void SetValue(Object*, Object*, BindingFlags, Binder*, Object*[], CultureInfo*) = 0;

[JScript] public abstract function SetValue(Object, Object, BindingFlags, Binder, Object[], CultureInfo);
