=>Create a Microsoft SQL Server database by using ADO.NET and Visual C# .NET

=>Steps to Create a SQL Server DatabaseTo create the database, follow these steps:

1. Create a new Visual C# .NET Windows application.

2. Place a button on Form1. Change the button's Name property to btnCreateDatabase, and then change the Text property to Create Database.

3. Use the using statement on the System and System.Data namespaces so that you do not have to qualify declarations in those namespaces later in your code.

Add the following code to the General Declarations section of Form1:

using System;
using System.Data.SqlClient;

Switch to Form view, and then double-click Create Database to add the click event handler. Add the following sample code to the handler:

String str; SqlConnection myConn = new SqlConnection ("Server=localhost;Integrated security=SSPI;database=master");

str = "CREATE DATABASE MyDatabase ON PRIMARY " + "(NAME = MyDatabase_Data, " + "FILENAME = 'C:\\MyDatabaseData.mdf', " + "SIZE = 2MB, MAXSIZE = 10MB, FILEGROWTH = 10%) " + "LOG ON (NAME = MyDatabase_Log, " + "FILENAME = 'C:\\MyDatabaseLog.ldf', " + "SIZE = 1MB, " + "MAXSIZE = 5MB, " + "FILEGROWTH = 10%)";

SqlCommand myCommand = new SqlCommand(str, myConn);

MessageBox.Show("DataBase is Created Successfully", "MyProgram", MessageBoxButtons.OK, MessageBoxIcon.Information);

catch (System.Exception ex)
MessageBox.Show(ex.ToString(), "MyProgram", MessageBoxButtons.OK, MessageBoxIcon.Information);


if (myConn.State == ConnectionState.Open)

4. Change the connection string to point to your computer running SQL Server, and then verify that the Database argument is set to Master or is blank.

5. Press F5 or CTRL+F5 to run the project, and then click Create Database.

6. Use the Server Explorer to verify that the database is created.

After creating DATABASE and Table in MS Sql Server then we create C# windows form then we click on insert button and write this code
String connectionstring="Data Source=ServerName;Initial Catalog=Databasename; User ID=UserName Password=Password";
SqlConnection cn=new SqlConnection(connectionstring);
String query="Sql insert command here";
SqlCommand cmd=new SqlCommand(query);
