C# 绑定通用集合列表<&燃气轮机;到属性网格
我尝试将generic collectionlistContact绑定到propGrid,但输出与我预期的不匹配。我希望listContact像ListBox一样显示在propGrid中。我该怎么做?多谢各位C# 绑定通用集合列表<&燃气轮机;到属性网格,c#,winforms,binding,collections,propertygrid,C#,Winforms,Binding,Collections,Propertygrid,我尝试将generic collectionlistContact绑定到propGrid,但输出与我预期的不匹配。我希望listContact像ListBox一样显示在propGrid中。我该怎么做?多谢各位 class Contact { public string Name { get; set; } public string Address { get; set; } } PropertyGrid propGrid = new PropertyGrid(); List&

您必须扩展类才能使用ExpandableObjectConverter
。这使得可解析的事件发生
请参阅下面的代码。只是一个例子。挑一个你最喜欢的。
用于编写以下代码的源代码:
[TypeConverter(typeof(Contact))]
[DescriptionAttribute(“展开以查看应用程序的拼写选项”。)]
类联系人:ExpandableObjectConverter
{
[DefaultValueAttribute(“联系人姓名”)]
公共字符串名称{get;set;}
公共字符串地址{get;set;}
公共覆盖布尔CanConvertTo(ITypeDescriptorContext上下文,类型destinationType)
{
如果(destinationType==typeof(联系人))
{
返回true;
}
返回base.CanConvertTo(上下文,destinationType);
}
公共重写对象转换为(ITypeDescriptorContext上下文,System.Globalization.CultureInfo区域性,对象值,类型destinationType)
{
if(destinationType==typeof(System.String)&&值为Contact)
{
触点触点=作为触点的值;
返回string.Format(“名称:{0}-地址:{1}”,contact.Name,contact.Address);
}
返回base.ConvertTo(上下文、区域性、值、destinationType);
}
}
[类型转换器(类型(触点2))]
[DescriptionAttribute(“展开以查看应用程序的拼写选项”。)]
