显示MySql服务器的数据库
本文关键字:数据库 服务器 MySql 显示 | 更新日期: 2023-09-27 18:11:36
有人知道,如何在c#中显示数据库吗?我知道这可能通过执行sql命令show databases
,但我不知道如何配置阅读器。谁来帮帮我。
EDIT: I found a solution:
private void Window_Loaded(object sender, RoutedEventArgs e)
{
MySqlConnection con = new MySqlConnection(this.constr);
MySqlCommand cmd = con.CreateCommand();
cmd.CommandText = "show databases";
try
{
con.Open();
MySqlDataReader reader = cmd.ExecuteReader();
while (reader.Read())
{
string row = "";
for (int i = 0; i < reader.FieldCount; i++)
row += reader.GetValue(i).ToString();
listBox1.Items.Add(row);
}
}
catch (MySqlException ex)
{
MessageBox.Show(ex.Number.ToString());
MessageBox.Show(ex.Message);
}
}
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();
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;
认为您可以查看数据行
也就是说,如果你已经有了连接字符串,没有理由不打开MSqlServer或其他从那里查看它…
