C# Combobox如何设置value

Answer 1

public class ComboxItem{public string Text {get; set;} public string Value{get; set;} public ComboxItem(string _Text, string _Value){Text = _Text; Value = _Value;}public override string ToString(){return Text;}}赋值 如下:combobox2.Items.Add(New ComboxItem("Text1", "Value1")); combobox2.Items.Add(New ComboxItem("Text2", "Value2")); combobox2.Items.Add(New ComboxItem("Text3", "Value3"));或者:ComboxItem[] x = { new ComboxItem("Text1", "Value1"), new ComboxItem("Text2", "Value2"), new ComboxItem("Text3", "Value1")};combobox2.Items.AddRange(x); 取值时需要转换一下 如下: string str = ((ComboxItem)combobox2.Items[0]).Value; 这个转换和你直接为Combobox控件绑定数据源是一样的. 如果你是这么绑定的数据 combobox2.DataSource = ds.Tables(0);//ds是dataset combobox2.DisplayMember = "TextCol"; combobox2.ValueMember = "ValueCol";那么得这么取值
