我有这段代码可以自动填充我的搜索文本框
AutoCompleteStringCollection coll = new AutoCompleteStringCollection();
DataTableReader reader=this.customerTableAdapter.GetData().CreateDataReader();
while(reader.Read()){
coll.Add(reader.GetString(0));
}
search.AutoCompleteCustomSource = coll;
是执行它的最佳方式吗?或者是否有一个函数使自动完成源直接成为列本身?
此外这个代码只过滤了第一个名字,但是当我使用gridview的这段代码时,它给了我更好的搜索能力,因此它捕获了名称的任何部分
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;
}

这段代码在不使用循环的情况下完成了这一操作,它在字符串数组中填充表的一列,然后用作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;
