Question

I need replace in my MySQL result “,” for “.”

string.Replace(",", ".");

current code:

mysql.Connection.Open();

        mysql.Command.CommandText = query;
        mysql.Reader = mysql.Command.ExecuteReader();

        string new_ = String.Empty;

        while (mysql.Reader.Read())
        {
            /*
            foreach(var field in mysql.Reader)
            {
               // what i do here?
            }
            */

            // here i have code to add to TextBox value
        }

I have no idea how to replace… i tried some like
field = string with replace
but Visual Studio cant take this code.

you probably wanna store all those replaced strings somewhere,

so you can make a list:

List<string> replacedStrings = new List<string>();
string replace = "";

     while (mysql.Reader.Read())
    {

        foreach(var field in mysql.Reader)
        {
          replace = field.replace(',','.');
          replacedStrings.add(replace); //<-- add each replaced string to the list
        }
     }
