Methods

CanConvertFrom(ITypeDescriptorContext, Type)

Returns whether this converter can convert an object of the given type to the type of this converter, using the specified context.

Declaration

public override bool CanConvertFrom(ITypeDescriptorContext context, Type sourceType)

Parameters

Type	Name	Description
System.ComponentModel.ITypeDescriptorContext	context	An System.ComponentModel.ITypeDescriptorContext that provides a format context.
System.Type	sourceType	A System.Type that represents the type you want to convert from.

Returns

Type	Description
System.Boolean	true if this converter can perform the conversion; otherwise, false.

ConvertFrom(ITypeDescriptorContext, CultureInfo, Object)

Converts the given object to the type of this converter, using the specified context and culture information.

Declaration

public override object ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, object value)

Parameters

Type	Name	Description
System.ComponentModel.ITypeDescriptorContext	context	An System.ComponentModel.ITypeDescriptorContext that provides a format context.
System.Globalization.CultureInfo	culture	The System.Globalization.CultureInfo to use as the current culture.
System.Object	value	The System.Object to convert.

Returns

Type	Description
System.Object	An System.Object that represents the converted value.

Exceptions

Type	Condition
System.NotSupportedException	The conversion cannot be performed.

ConvertTo(ITypeDescriptorContext, CultureInfo, Object, Type)

Converts the given value object to the specified type, using the specified context and culture information.

Declaration

public override object ConvertTo(ITypeDescriptorContext context, CultureInfo culture, object value, Type destinationType)

Parameters

Type	Name	Description
System.ComponentModel.ITypeDescriptorContext	context	An System.ComponentModel.ITypeDescriptorContext that provides a format context.
System.Globalization.CultureInfo	culture	A System.Globalization.CultureInfo. If null is passed, the current culture is assumed.
System.Object	value	The System.Object to convert.
System.Type	destinationType	The System.Type to convert the value parameter to.

Returns

Type	Description
System.Object	An System.Object that represents the converted value.

Exceptions

Type	Condition
System.ArgumentNullException	The destinationType parameter is null.
System.NotSupportedException	The conversion cannot be performed.

CreateInstance(ITypeDescriptorContext, IDictionary)

Creates an instance of the type that this System.ComponentModel.TypeConverter is associated with, using the specified context, given a set of property values for the object.

Declaration

public override object CreateInstance(ITypeDescriptorContext context, IDictionary propertyValues)

Parameters

Type	Name	Description
System.ComponentModel.ITypeDescriptorContext	context	An System.ComponentModel.ITypeDescriptorContext that provides a format context.
System.Collections.IDictionary	propertyValues	An System.Collections.IDictionary of new property values.

Returns

Type	Description
System.Object	An System.Object representing the given System.Collections.IDictionary, or null if the object cannot be created. This method always returns null.

GetCreateInstanceSupported(ITypeDescriptorContext)

Returns whether changing a value on this object requires a call to System.ComponentModel.TypeConverter.CreateInstance(System.Collections.IDictionary) to create a new value, using the specified context.

Declaration

public override bool GetCreateInstanceSupported(ITypeDescriptorContext context)

Parameters

Type	Name	Description
System.ComponentModel.ITypeDescriptorContext	context	An System.ComponentModel.ITypeDescriptorContext that provides a format context.

Returns

Type	Description
System.Boolean	true if changing a property on this object requires a call to System.ComponentModel.TypeConverter.CreateInstance(System.Collections.IDictionary) to create a new value; otherwise, false.

GetProperties(ITypeDescriptorContext, Object, Attribute[])

Returns a collection of properties for the type of array specified by the value parameter, using the specified context and attributes.

Declaration

public override PropertyDescriptorCollection GetProperties(ITypeDescriptorContext context, object value, Attribute[] attributes)

Parameters

Type	Name	Description
System.ComponentModel.ITypeDescriptorContext	context	An System.ComponentModel.ITypeDescriptorContext that provides a format context.
System.Object	value	An System.Object that specifies the type of array for which to get properties.
System.Attribute[]	attributes	An array of type System.Attribute that is used as a filter.

Returns

Type	Description
System.ComponentModel.PropertyDescriptorCollection	A System.ComponentModel.PropertyDescriptorCollection with the properties that are exposed for this data type, or null if there are no properties.

GetPropertiesSupported(ITypeDescriptorContext)

Returns whether this object supports properties, using the specified context.

Declaration

public override bool GetPropertiesSupported(ITypeDescriptorContext context)

Parameters

Type	Name	Description
System.ComponentModel.ITypeDescriptorContext	context	An System.ComponentModel.ITypeDescriptorContext that provides a format context.

Returns

Type	Description
System.Boolean	true if System.ComponentModel.TypeConverter.GetProperties(System.Object) should be called to find the properties of this object; otherwise, false.
