我需要在内存中使用基于来自 GridView 的列和方向的 DataTable.该函数需要如下所示:
I need to resort, in memory, a DataTable based on a column and direction that are coming from a GridView. The function needs to look like this:
public static DataTable resort(DataTable dt, string colName, string direction) { DataTable dtOut = null; .... }我需要帮助填写此功能.我想我可以使用 Select 语句,但我不确定如何.由于此浏览器,我无法单击评论",但您可以向我展示就地或新的 DataTable 解决方案,任一种.请给我指点的人,我需要一个类似于原型的编码函数.
I need help filling in this function. I think I can use a Select statement but I am not sure how. I can't click on Comments because of this browser but you can show me an in-place or new DataTable solution, either one. For the people showing me pointers, please, I need a coded function similar to the one prototyped.
怎么样:
// ds.Tables[0].DefaultView.Sort="au_fname DESC"; public static void Resort(ref DataTable dt, string colName, string direction) { string sortExpression = string.Format("{0} {1}", colName, direction); dt.DefaultView.Sort = sortExpression; } 推荐答案我假设direction"是ASC"或DESC"并且dt包含一个名为colName"的列
I assume "direction" is "ASC" or "DESC" and dt contains a column named "colName"
public static DataTable resort(DataTable dt, string colName, string direction) { DataTable dtOut = null; dt.DefaultView.Sort = colName + " " + direction; dtOut = dt.DefaultView.ToTable(); return dtOut; }或不创建 dtOut
public static DataTable resort(DataTable dt, string colName, string direction) { dt.DefaultView.Sort = colName + " " + direction; dt = dt.DefaultView.ToTable(); return dt; }更多推荐
如何对给定列和方向的 DataTable 进行排序?
