Append values to existing array

Append values to existing array

Padmanabhan, Venkatesh 125

Hi. I am looping through the contents using a for each loop and storing the value in string array. Even though the loop is going more than thrice, only the last loop data is getting stored in the string array. How to store all the values in the array ? Below is the code which is used :

 string[] values = new string[] { };
                var applicationSettings = ConfigurationManager.GetSection(ddlAppln.SelectedValue.ToString().Trim()) as NameValueCollection; 

                if (applicationSettings.Count == 0)
                {
                    Console.WriteLine("Application Settings are not defined");
                }
                else
                {
                    foreach (var key in applicationSettings.AllKeys)
                    {                        
                        values =  applicationSettings[key].ToString().Split(',');
                    }
                }

Hi, welcome to Microsoft Q&A.

You can use append method to add each string to values.

Check the following code.

            string[] values = new string[] { };
            var applicationSettings = ConfigurationManager.GetSection(ddlAppln.SelectedValue.ToString().Trim()) as NameValueCollection;

            if (applicationSettings.Count == 0)
            {
                Console.WriteLine("Application Settings are not defined");
            }
            else
            {
                foreach (var key in applicationSettings.AllKeys)
                {
                    foreach(string str in applicationSettings[key].ToString().Split(','))
                    {
                        values = values.Append<string>(str).ToArray();
                    }
                    
                }
            }

Best Regards.
