Show databases of MySql server
11,525
Solution 1
string myConnectionString = "SERVER=localhost;UID='root';" + "PASSWORD='root';";
MySqlConnection connection = new MySqlConnection(myConnectionString);
MySqlCommand command = connection.CreateCommand();
command.CommandText = "SHOW DATABASES;";
MySqlDataReader Reader;
connection.Open();
Reader = command.ExecuteReader();
while (Reader.Read())
{
string row = "";
for (int i = 0; i < Reader.FieldCount; i++)
row += Reader.GetValue(i).ToString() + ", ";
comboBox1.Items.Add(row);
}
connection.Close();
Solution 2
SqlConnection conn = new SqlConnection(ConnectionString);
SqlCommand com = new SqlCommand ("show databases",conn);
conn.Open();
SqlDataReader reader = com.ExecuteReader();
DataTable dt = new DataTable;
dt.Load(reader);
DataRows[] rows = dt.Rows;
Think you can then view the data rows
That said, if you already have the connection string, there's no reason not to open MSqlServer or whatever and view it from there...
