How to C# Socket Programming using Visual Studio.Net

Learn step by step network programming using C#.Net socket, remoting, WCF and SignalR technology from lots of source code and description. All source code download link available at end of the blog post.

Run any Stored Procedure from .Net

Hi, Now I’m far from socket now Im giving some code with .Net and SQL Server related code, that code will help any one to run stored procedure, very easyly with little code. Now follow these code.

Create a table to test the stored procedure, I’m giving one example:

CREATE TABLE client(
id int IDENTITY(1,1) NOT NULL,
Name varchar(64) NULL,
jdate datetime NULL
)

Then insert some data into that table.

INSERT INTO client(Name,jdate)VALUES ('Taniya',getdate())
INSERT INTO client(Name,jdate)VALUES ('Jhuma',getdate())
INSERT INTO client(Name,jdate)VALUES ('Ganesh',getdate())


Then create a stored procedure to test my class, here I’m creating a stored procedure (sp) to update some data based on client id. Here store procedure’s parameters are @nextName and @id. Code is giving here:

create procedure UpdateName ( @nextName varchar(256), @id int )
as
update client set name=@nextName where id=@id


Now sql server data base related job is done. Now will to c# related code.

First giving the code by that my class will be accessed to run that stored procedure. Just note that code, only that code will be required to run any stored procedure.

public class RunSP
{
/// *summary$
/// Run Store Procedure.
/// */summary$
/// *param name="cnnStr"$Connection String of SQL server*/param$
public static void RunSP(string cnnStr)
{
//Create a array list to store parameter(s) with
//parameter name, value & data type.
ArrayList arLst = new ArrayList();
//Now send array list name, value & varchar, persingle
//call of that function will create one stored parameter.
SP.spArgumentsCollection(arLst, "@nextName", "Suman Biswas", "varchar");
SP.spArgumentsCollection(arLst, "@id", "2", "int");
//Now run stored procedure.
SP.RunStoredProcedure(cnnStr, "UpdateName", arLst);
}
}


Here the actual class to run stored procedure, you can make all dll file by that code and then easily use this. Codes are below:

using System;
using System.Collections.Generic;
using System.Text;
using System.Collections;
using System.Data;
using System.Data.SqlClient;

//That code has written by Suman Biswas, that code is running fine at my testing,
//if any one get any problem please inform me. My email is sumanbiswas@aol.in
