Data 　(i). Description There is a problem with programming: Occasionally, for some reason, a database table needs to be changed to a field name. For example: change: Name to: PersonName. The programmer then turns on all the code involved and finds something similar: DS. Table[0]. row[n][the statement "Name", modified to: DS. Table[0]. row[n]["Name"]. In fact, there is no need to do so, just add a structure with a dataset on the OK. Modifying only one

Ado New features of Ado.net 2.0 dataset and DataTable 1. Faster execution efficiency of the new indexing engineThe following code takes 157 seconds in 2003 and can be completed in 2005 in 11 seconds: DataSet ds = new DataSet (); Ds. Tables.add ("BigTable");Ds. Tables[0]. Columns.Add ("ID", Type.GetType ("System.Int32"));Ds. Tables[0]. columns["ID"]. Unique = true

Public JsonResult Test () {JsonResult json = new JsonResult {Data = new {Name = "zzl", Sex = "male" ,}}; return Json (json );} public JsonResult TestList () {List method of List 2, you can also achieve this in a simpler way: Public JsonResult TestList () {List Var arr = [{"name": "zzl", "sex": "male" },{ "name": "lr", "sex ": "female"}]; for (var I = 0; I DataSet is a method used to connect to SQL. It means that a copy of the database tutorial is

DataSetRepresents the cache of data in memory. PropertyTables gets a collection of tables that are contained in the DataSet. Ds. tables["SJXX"] DataTable Represents a table of data in memory. Public propertiesColumns gets the collection of columns that belong to the table. The dataset obtains the dataset to which this table belongs. DefaultView gets a cu

XML this time to write the project every time to use XML to save some configuration, and each operation of XML is very cumbersome, no database so smooth. It was later discovered that using a dataset to manipulate XML was convenient and flexible, so it wrote a class that manipulated XML to deal with general XML operations (source download attachments). 1 Basic IdeasIn fact, using dataset to manipulate XML, i

Check for changes with the HasChanges method. First use the HasChanges method to detect the affected rows (return bool) if (!mydataset.haschanges (datarowstate.modified)) return; To create a temporary dataset DataSet Xdataset; Using the GetChanges method of the dataset to get the affected rows Xdataset = Mydataset.getchanges (datarowstate.modified); detecting

xml| Original This time the project writes each time to use the XML to save some configuration, but each operation XML is very troublesome, does not have the database so conveniently. It was later discovered that using a dataset to manipulate XML was convenient and flexible, so it wrote a class that manipulated XML to deal with general XML operations (source download attachments). 1 Basic IdeasIn fact, using datas
