[英]Winforms combobox displaying class names instead of actual object name
I have this class that contains a static list我有这个 class 包含一个 static 列表
public class TypeList
{
public string Name;
public string NameTag;
public TypeList(string Name, string NameTag)
{
this.Name = Name;
this.NameTag = NameTag;
}
public static List<TypeList> DataType = new List<TypeList>() {
new TypeList("DataType","-1"),
new TypeList("OpOne","1"),
new TypeList("OpTwo","2"),
};
}
I then put the static list called DataType into a combobox:然后我将名为 DataType 的 static 列表放入 combobox 中:
public void RefreshList()
{
List<TypeList> data = new List<TypeList>();
data = TypeList.DataType;
typeCB.DataSource = data;
typeCB.DisplayMember = "Name";
typeCB.ValueMember = "NameTag";
typeCB.SelectedValue = -1;
typeCB.SelectedText = "Select DataType";
}
However, when I run it, all I get are the classnames in my combobox.但是,当我运行它时,我得到的只是 combobox 中的类名。 Is something wrong with my code?
我的代码有问题吗? I tried to do
我试着做
data.Select(x=>x.Name).ToList()
data.Select(x=>x.Name).ToList()
But that just gives me the name portion.但这只是给了我名字部分。
I might be wrong, but based on the Documentation and Example it might be that this Feature only works with public property getters, not public fields:我可能错了,但根据文档和示例,此功能可能仅适用于公共属性获取器,而不适用于公共字段:
Gets or sets the property to display for this ListControl.
获取或设置要为此 ListControl 显示的属性。
public class USState
{
private string myShortName;
private string myLongName;
public USState(string strLongName, string strShortName)
{
this.myShortName = strShortName;
this.myLongName = strLongName;
}
public string ShortName
{
get
{
return myShortName;
}
}
public string LongName
{
get
{
return myLongName;
}
}
}
Of course I would also advise against making the list a part of the Type class.当然,我也建议不要将列表作为 class 类型的一部分。 A simple Programm scope static would be better.
一个简单的程序 scope static 会更好。 If that is the case and as autoproties have have become a thing by now, this should be enough of a fix:
如果是这样的话,并且现在自动特性已经成为一种东西,这应该足以解决问题:
public class Type
{
public string Name { private set; get } ;
public string NameTag {private set; get };
public TypeList(string Name, string NameTag)
{
this.Name = Name;
this.NameTag = NameTag;
}
}
//use in the class of main, the form or some similar central point
static List<Type> TypeList = new List<Type>();
