Embodiment

[0014] end:

[0015] 1. First, serialize the DataTable into a string, and save the table name, column name and other information in the string string. Part of the code is as follows:

[0016] Private static string SerializeDataTable(Datatable dt, int ipIndex)

[0017] {

[0018] try

[0019] {

[0020] StringBuilder strResult = new StringBuilder()

[0021] String strTableName = "";

[0022] StrtablName=dt.TableName;

[0023] If (strTableName=="")

[0024] StrtablName="TABLENAME_"+ipIndex, ToString();

[0025] strResult.Appdend("▲");

[0026] for(int s=0:s

[0027] strResult.Appdend(dt.Columns[s].ColumnName);

[0028] 2. Encode and compress the obtained string:

[0029] Byte[]bytes=System.Text.Encoding.UTF8.GetBytes(str);

[0030] Byte[]bR=Utils. Compress(bytes);

[0031] Return System.Convert.ToBase64String(bR)

[0032] Silverlight side:

[0033] First, decode and decompress the string, and parse ...

Abstract

The invention provides a method for a dynamically creating entity class under a frame of Silverlight. According to the method, a data table type sequence not supported by the Silverlight is transformed to a character string type sequence supported by the Silverlight through the method of sequence transformation at a WCF side. The method comprises the steps: (1) a data table is serialized to be a character string through a server side and transmitted to a Silverlight side through the WCF after compression; (2) the character string is decoded and uncompressed at the Silverlight side, the uncompressed character string is analyzed so that Observable Collection (dynamic) is obtained, wherein the dynamic is of a dynamic type, and data of the data table are stored through the Observable Collection (dynamic); and (3) according to analyzed information, a case is dynamically established and assigned so that transformation of the character string type sequence is achieved, and at last the transformed character string type sequence is returned to the Silverlight side for use.

Description

technical field [0001] The invention relates to the technical field of computer applications, in particular to a method for dynamically creating entity classes under the silverlight framework. Background technique [0002] DataTable is a grid virtual table that temporarily saves data, and it can be easily bound to the database without code. We know that entity tables are stored in the database, and there are a series of data in entity tables. The DataTable is a table stored in memory, and it will not affect the database until it is persisted to the database. DataTable is often used in project development. If DataTable is used properly, it can not only make the program simple and practical, but also improve performance and achieve twice the result with half the effort. DataTable also has many methods, such as: 1. Get DataTable through constructor; 2. Get DataTable through DataSet; 3. Customize the structure of DataTable through DataRow; 4. Get new DataTable through existing...
