快速搜索.net(c#和vb.net)winforms [英] fast search in .net (c# and vb.net) winforms
问题描述
你好
i存储阵列中的一些物品(或组合框)
i想要快速搜索其中的物品。
以下代码搜索所有项目,需要多次。我想要快速搜索
string _search_items ='computer'
for(int i = 0; i< combobox.items.count ; i ++)
{
if(combobox.items [i] == _search_items)
ok;
}
如何快速访问项目而不搜索所有项目?
谢谢。
hello
i store some items in a array (or in combobox)
i wants to search an items in them fastly.
the following code search all items and it's take several times . i want have a fast search
string _search_items='computer'
for (int i=0 ; i< combobox.items.count; i++)
{
if (combobox.items[i] == _search_items)
ok;
}
how can i access to item fastly without search all items?
thanks.
推荐答案
string _search_items='computer'
for (int i=0 ; i< combobox.items.count; i++)
{
if (combobox.items[i] == _search_items)
ok; //agreed
break;
}
//or this Try to have your combobox elements sorted like
// A B C D
Try .......
BindingSource src = new BindingSource();
src.DataSource = new Hashtable(); // fill it with ur data
comboBox1.DataSource = src;
comboBox1.ValueMember = "Key";
comboBox1.DisplayMember = "Value.DisplayName
将hastable与作为数据源的组合框绑定后,你可以找到任何0(1)项的复杂性。
After binding a hastable to your combobox as datasource, u can find any item 0(1) complexity.
