我如何逐行读取texfile并使用C＃添加到数组

Question

Am using AfricasTalking C# class to send Airtime. First you create and array of numbers to send airtime. Below is a code to create Arraylist. Instead i want to read numbers from a text file and add to rec1.

ArrayList AirtimeRecipientsList = new ArrayList();

// Declare hashtable to hold the first number
// Please ensure you include the country code for phone numbers (+254 for Kenya in this case)
// Please ensure you include the country code for phone numbers (KES for Kenya in this case)
// Specify the country currency and the amount as shown below

Hashtable rec1 = new Hashtable();
rec1["phoneNumber"] = txtPhoneNo.Text;
rec1["amount"] = "KES "+ txtAmount.Text;

// Add recipient to list
AirtimeRecipientsList.Add(rec1);

// Declare hashtable to hold the another number
//Hashtable rec2 = new Hashtable();
//rec2["phoneNumber"] = "+254733YYYZZZ";
//rec2["amount"] = "KES XXX";

// Add recipient to list
//AirtimeRecipientsList.Add(rec2);`

Answer 1

Assuming your text file has phone number and amount separated by comma or any character like this "123456789, KES 500" on each line without quotes. Here is some code.

    var recipients = System.IO.File.ReadAllLines(path to text file);
    ArrayList recipientsList = new ArrayList();
     foreach(var line in recipients)
         { 
           Hashtable rec1 = new Hashtable();
          rec1["phoneNumber"] = line.Split(',')[0];
          rec1["amount"] = line.Split(',')[1];
           recipientsList.Add(rec1)
         }

That's it.
