ConfigurationConverterBase.CanConvertFrom Method

Definition

Namespace:

System.Configuration

Assembly:

System.Configuration.ConfigurationManager.dll

Determines whether the conversion is allowed.

public:
 override bool CanConvertFrom(System::ComponentModel::ITypeDescriptorContext ^ ctx, Type ^ type);

public override bool CanConvertFrom (System.ComponentModel.ITypeDescriptorContext ctx, Type type);

override this.CanConvertFrom : System.ComponentModel.ITypeDescriptorContext * Type -> bool

Public Overrides Function CanConvertFrom (ctx As ITypeDescriptorContext, type As Type) As Boolean

Parameters

ctx

ITypeDescriptorContext

The ITypeDescriptorContext object used for type conversions.

type

Type

The Type to convert from.

Returns

Boolean

true if the conversion is allowed; otherwise, false.

Examples

The following example code shows how to override the CanConvertFrom method to create a custom TimeSpan converter type. Also, the example shows how to use this type in a custom section.

public override bool CanConvertFrom(
    ITypeDescriptorContext ctx, Type type)
{
    return (type == typeof(string));
}

Public Overrides Function CanConvertFrom( _
ByVal ctx As ITypeDescriptorContext, _
ByVal type As Type) As Boolean
    Return (type.ToString() = GetType(String).ToString())

End Function 'CanConvertFrom

Remarks

The CanConvertFrom method determines whether a conversion can be performed on strongly typed properties to obtain value strings used in the configuration file.
