ALTER DATABASE database-name SET READ_ONLY

ALTER DATABASE database-name SET READ_WRITE

您可以像下面那样在 c# 中访问存储过程以执行以上几行.

You can access the stored procedure in c# like below to execute the above lines.

using (System.Data.SqlClient.SqlConnection con = new SqlConnection("YourConnection string")) {
    con.Open();
    SqlCommand cmd = new SqlCommand();
    string expression = "Parameter value";
    cmd.CommandType = CommandType.StoredProcedure;
    cmd.CommandText = "Your Stored Procedure";
    cmd.Parameters.Add("Your Parameter Name", SqlDbType.VarChar).Value = expression;
    cmd.Connection = con;
    using (IDataReader dr = cmd.ExecuteReader()) {
        if (dr.Read()) {
        }
    }
}
