化妆自动完成文本框形成C＃

Question

我有这样的一段代码自动完成我的搜索文本框

AutoCompleteStringCollection coll = new AutoCompleteStringCollection(); 
     DataTableReader reader=this.customerTableAdapter.GetData().CreateDataReader(); 
     while(reader.Read()){ 
      coll.Add(reader.GetString(0)); 
     } 

     search.AutoCompleteCustomSource = coll; 

是最好的方式来执行呢？或者是否有一个函数直接使自动完成源自己的列本身？

而且这个代码仅过滤头名，但是当我使用这段代码的GridView它给了我更好的搜索能力，所以它抓住了名的任何部分

private void search_KeyUp(object sender, KeyEventArgs e) 
    { 
     string outputInfo = ""; 
     string[] keyWords = search.Text.Split(' '); 

     foreach (string word in keyWords) 
     { 
      if (outputInfo.Length == 0) 
      { 
       outputInfo = "(Name LIKE '%" + word + "%')"; 
      } 
      else 
      { 
       outputInfo += " AND (Name LIKE '%" + word + "%')"; 
      } 
     } 

     //Applies the filter to the DataView 
     myView.RowFilter = outputInfo; 
    } 

建议请

这段代码这样的伎俩没有使用循环，它填补了字符串数组表中的一列，然后将其作为autoCompleteSource

  DataTable dt = this.data_allDataSet.merchandise; 
     //use LINQ method syntax to pull the Title field from a DT into a string array... 
     string[] postSource = dt 
          .AsEnumerable() 
          .Select<System.Data.DataRow, String>(x => x.Field<String>("name")) 
          .ToArray(); 

     var source = new AutoCompleteStringCollection(); 
     source.AddRange(postSource); 
     cat_name.AutoCompleteCustomSource = source; 
     cat_name.AutoCompleteMode = AutoCompleteMode.Suggest; 
     cat_name.AutoCompleteSource = AutoCompleteSource.CustomSource;
