C#实现绑定Combobox的方法

public class StaticVariable{  public Dictionary<string, string> tabTypeArray;  public Dictionary<string, string> transTimeArray;  public Dictionary<string, string> fileDealTypeArray;  public StaticVariable()  {   tabTypeArray = new Dictionary<string, string>();     tabTypeArray.Add("1", "定长类型");   tabTypeArray.Add("2", "非定长类型");   tabTypeArray.Add("3", "手册压缩文件");   tabTypeArray.Add("4", "dutyForm");   tabTypeArray.Add("10", "Bulletin");   tabTypeArray.Add("0", "未知类型");   transTimeArray = new Dictionary<string, string>();   transTimeArray.Add("-1", "实时处理");   transTimeArray.Add("0", "不处理");   fileDealTypeArray = new Dictionary<string, string>();   fileDealTypeArray.Add("0", "普通文件");   fileDealTypeArray.Add("1", "增量文件");  }}void BinderCombobox(){ Common.StaticVariable staticVariable = new InsetApplication.Common.StaticVariable(); foreach (string key in staticVariable.tabTypeArray.Keys) {  cbTabType.Items.Add(new DictionaryEntry(key, staticVariable.tabTypeArray[key])); } foreach (string key in staticVariable.transTimeArray.Keys) {  cbTransTime.Items.Add(new DictionaryEntry(key, staticVariable.transTimeArray[key])); } foreach (string key in staticVariable.fileDealTypeArray.Keys) {  cbDealType.Items.Add(new DictionaryEntry(key, staticVariable.fileDealTypeArray[key])); } cbDealType.DisplayMember = "value"; cbDealType.ValueMember = "key"; cbTabType.DisplayMember = "value"; cbTabType.ValueMember = "key"; cbTransTime.DisplayMember = "value"; cbTransTime.ValueMember = "key"; if (cbTransTime.Items.Count > 0)  cbTransTime.SelectedIndex = 0; if (cbDealType.Items.Count > 0)  cbDealType.SelectedIndex = 0; if (cbTabType.Items.Count > 0)  cbTabType.SelectedIndex = 0;}
