Explanation / Answer

For developing the voting system, Firstly you need to set-up an Database for the Voting Application.

Here, I will explain you about the C# code along with the comments.

One Class for Implementation: -

Program:

// Created a method named EligibleVoter

private void EligibleVoter(string vID)
{
// This is to connect your database to the c# code

SqlConnection conn = new SqlConnection(WebConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);

   // I have created the table name Votes and column_name as CountVotes along with the vID as primary key

SqlCommand cmd = new SqlCommand("UPDATE Votes SET CountVotes = CountVotes+1 WHERE vID=@vID", conn);
cmd.CommandType = CommandType.Text;

cmd.Parameters.AddWithValue("@vID", vID);

using (conn)
{
//Now, it will open and connect to the database
conn.Open();

       // This statement is used to execute the update query which we have written at top

cmd.ExecuteNonQuery();
}

protected void btn_Click(object sender, EventArgs e)
{

EligibleVoter("A");
}

One Class for Testing: -

Program:
