DataTable与List<T>互转 1.List<T>转DataTable public static DataTable ListToDataTable<T>(List<T> list) { ) { return new DataTable(); } //获取T下所有的属性 Type entityType = list[].GetType(); PropertyInfo[] entityProperties = entityType.GetProper…

1.DataTable转换成XML public string ConvertDataTableToXML(DataTable xmlDS) { MemoryStream stream = null; XmlTextWriter writer = null; try { stream = new MemoryStream(); writer = new XmlTextWriter(stream, Encoding.UTF8); xmlDS.WriteXml(writer); int count…

之前做DataTable和DataSet转xml一直使用XmlSerializer 序列化完成.今天发现新方法,哇咔咔方便了很多.还不用担心Name为空时报错 static void Main(string[] args) { DataTable dt = new DataTable(); dt.TableName = "dtABC"; dt.Columns.Add("CloumnA"); dt.Columns.Add("CloumnB"); d…

本篇把项目中用到的一些通用方法总结出来, 这些方法因为经常需要在项目中用到,所以把它们归纳在一起, 形成一个.dll 文件是一个理想的选择. 这样也便于日后缩短开发周期. 一. 把一个DataGridView对象转换成一个DataTable对象 public static DataTable GetDgvToTable(DataGridView dgv)   {           if(dgv==null) throw new NullReferenceException();        …
