Examples

   // Associates the DataMemberConverter with a string property.
public:
   [TypeConverterAttribute(DataMemberConverter::typeid)]
   property String^ dataMember 
   {
      String^ get()
      {
         return member;
      }
      void set( String^ value )
      {
         member = value;
      }
   }
private:
   String^ member;

// Associates the DataMemberConverter with a string property.
[TypeConverterAttribute(typeof(DataMemberConverter))]
public string dataMember
{
    get
    {
        return member;
    }
    set

        member = value;
    }
}

' Associates the DataMemberConverter with a string property.

Private member As String

Remarks

DataMemberConverter provides methods that can retrieve a list of data members from the current data source of a design-time component.

This type converter is used by Visual Studio 2005 to provide the values that appear in the list of data members in the Properties window.

Caution

You should never access a type converter directly. Instead, call the appropriate converter by using TypeDescriptor. For more information, see the examples in the TypeConverter base class.

For more information about type converters, see the TypeConverter base class and How to: Implement a Type Converter.

Constructors

DataMemberConverter()

Initializes a new instance of the DataFieldConverter class.

Methods

CanConvertFrom(ITypeDescriptorContext, Type)	Gets a value indicating whether the converter can convert an object of the specified source type to the native type of the converter.
CanConvertFrom(Type)	Returns whether this converter can convert an object of the given type to the type of this converter. (Inherited from TypeConverter)
CanConvertTo(ITypeDescriptorContext, Type)	Returns whether this converter can convert the object to the specified type, using the specified context. (Inherited from TypeConverter)

ConvertFrom(ITypeDescriptorContext, CultureInfo, Object)	Converts the specified object to the native type of the converter.
ConvertFrom(Object)	Converts the given value to the type of this converter. (Inherited from TypeConverter)
ConvertFromInvariantString(ITypeDescriptorContext, String)	Converts the given string to the type of this converter, using the invariant culture and the specified context. (Inherited from TypeConverter)
