我将 linq 结果数据绑定到数据网格,但没有任何结果。这是我的代码
List<SearchResult> list = new List<SearchResult>() {
new SearchResult(){ID=1,Title="Geo Prism 1995 GEO* - ABS #16213899"},
new SearchResult(){ID=2,Title="Excavator JCB - ECU P/N: 728/35700"},
new SearchResult(){ID=3,Title="Geo Prism GEO 1995 - ABS #16213899"},
new SearchResult(){ID=4,Title="JCB Excavator JCB- ECU P/N: 728/35700"},
new SearchResult(){ID=5,Title="Geo Prism GEO,GEO 1995 - ABS #16213899 GEO"},
new SearchResult(){ID=6,Title="dog"},
};
var to_search = new[] { "Geo", "JCB" }.Select(x => x.ToLower()).ToArray();
var result = from searchResult in list
let title = searchResult.Title.ToLower()
let key_string = to_search.FirstOrDefault(ts => title.Contains(ts))
orderby key_string == null ? -1 : title.Split(new[] { key_string }, StringSplitOptions.None).Length descending
group searchResult by key_string into Group
orderby Group.Count() descending
select Group;
dataGridView2.DataSource = result;
当我运行上面的代码 datagrid 什么都没有显示,但我期望 datagrid 应该显示ID 和 Title
然后我添加了更多的行
List<SearchResult> listFinal = new List<SearchResult>();
foreach (var group in result)
{
foreach (var item in group)
{
listFinal.Add(new SearchResult() { ID = item.ID, Title = item.Title });
}
}
dataGridView2.DataSource = listFinal;
现在 datagrid 正在显示数据。所以我的问题是......是否有任何捷径可以将结果转换为列表,因此我可以通过循环迭代将列表直接绑定到数据网格并创建一个新列表并在绑定之前将其填充。寻求指导。谢谢
