See the below code :

Dim SQLString As String = “SELECT Count(*) FROM tableName“
Dim yourDBConnection As New SqlConnection()
yourDBConnection.ConnectionString = yourConnectionString

 Dim cmd As New SqlCommand()
Dim recCount As Integer

yourDBConnection.Open()

cmd.Connection = yourDBConnection
 cmd.CommandText = SQLString 
 recCount = Integer.Parse(cmd.ExecuteScalar().ToString)

yourDBConnection.Close()

Open in new window

Converted to c# :

string SQLString = "SELECT Count(*) FROM tableName";
SqlConnection yourDBConnection = new SqlConnection();
yourDBConnection.ConnectionString = yourConnectionString;

SqlCommand cmd = new SqlCommand();
int recCount = 0;

yourDBConnection.Open();

cmd.Connection = yourDBConnection;
cmd.CommandText = SQLString;
recCount = int.Parse(cmd.ExecuteScalar().ToString);

yourDBConnection.Close();

Open in new window
