IconConverter.CanConvertFrom(ITypeDescriptorContext, Type) 方法
定义
使用指定的上下文确定此 IconConverter 是否能够将指定类型的实例转换为 Icon。Determines whether this IconConverter can convert an instance of a specified type to an Icon, using the specified context.
public:
override bool CanConvertFrom(System::ComponentModel::ITypeDescriptorContext ^ context, Type ^ sourceType);
public override bool CanConvertFrom (System.ComponentModel.ITypeDescriptorContext context, Type sourceType);
override this.CanConvertFrom : System.ComponentModel.ITypeDescriptorContext * Type -> bool
Public Overrides Function CanConvertFrom (context As ITypeDescriptorContext, sourceType As Type) As Boolean
参数
- context
- ITypeDescriptorContext
一个 ITypeDescriptorContext,用于提供格式上下文。An ITypeDescriptorContext that provides a format context.
返回
如果此 IconConverter 可以执行转换,则此方法返回 true;否则返回 false。This method returns true if this IconConverter can perform the conversion; otherwise, false.
注解
true仅当 sourceType 等于字节数组时,此方法才会返回。This method returns true only if sourceType is equal to a byte array.
