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
The ITypeDescriptorContext object used for type conversions.
true
if the conversion is allowed; otherwise, false
.
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
The CanConvertFrom method determines whether a conversion can be performed on strongly typed properties to obtain value strings used in the configuration file.
