  • Reference

Definition

Namespace:
System.Web.Configuration
Assembly:
System.Web.dll

Converts an object to a lowercase string based on the specified parameters.

public:
 override System::Object ^ ConvertTo(System::ComponentModel::ITypeDescriptorContext ^ ctx, System::Globalization::CultureInfo ^ ci, System::Object ^ value, Type ^ type);
public override object ConvertTo (System.ComponentModel.ITypeDescriptorContext ctx, System.Globalization.CultureInfo ci, object value, Type type);
override this.ConvertTo : System.ComponentModel.ITypeDescriptorContext * System.Globalization.CultureInfo * obj * Type -> obj
Public Overrides Function ConvertTo (ctx As ITypeDescriptorContext, ci As CultureInfo, value As Object, type As Type) As Object

Parameters

ctx
ITypeDescriptorContext

An object that implements the ITypeDescriptorContext interface.

ci
CultureInfo

An object that implements the CultureInfo class.

value
Object

The object to convert.

type
Type

The type of object to convert.

Returns

Object

A lowercase string object.

Examples

The following example demonstrates how to use this method.

// ConvertTo method.
Console.WriteLine("Original Value: {0}",
  testStrVal.ToString());
resultStrVal = myLCStrConverter.ConvertTo
  (ctx,ci,testStrVal, testStrVal.GetType());
Console.WriteLine("ConvertTo result: {0}",
  resultStrVal.ToString());

' ConvertTo method.
Console.WriteLine("Original Value: {0}", _
  testStrVal.ToString())
resultStrVal = myLCStrConverter.ConvertTo _
  (ctx, ci, testStrVal, testStrVal.GetType())
Console.WriteLine("ConvertTo result: {0}", _
  resultStrVal.ToString())

Remarks

This method uses an object that implements the ITypeDescriptorContext interface as the ctx parameter. This interface provides contextual information about a component. Typically, this interface is used at design time to provide information about a design-time container. The ITypeDescriptorContext is commonly used in type conversion. The ci parameter object provides the culture-related information. The value object acts as both the object to convert and the resulting object once the method is complete. Override this method in a derived class if custom behavior is required.
