In my C# windows form I have 2 forms. I would like to display a collection of strings in a label on a form. When I debug I show the 2 elements in my array but they are not showing in the label I am passing it to. When I hover of toString the data is there but how to I pass it to sender so it will display in the label control I have on my form?

In the snippet of code below to data is in toString but how do I get it from there down to sender.ToString????

 public AccountReport_cs(Func<string> toString)
 
 this.toString = toString;


 

 private void AccountReport_cs_Load(object sender, EventArgs e)
 

 label1.Text = sender.ToString();
 

This is another piece of the code that will open form2 where the information should be displayed.

 private void reportButton2_Start(object sender, EventArgs e)
 
 AccountReport_cs accountReport = new AccountReport_cs(allTransactions.ToString);
 accountReport.ShowDialog();
 

Here is the last piece of code and this will show how the data gets to EndOfMonth.

 public class Transaction

 public string EndOfMonth get; set; 


 public override List<Transaction> closeMonth()
 
 var transactions = new List<Transaction>();
 var endString = new Transaction();

 endString.EndOfMonth = reportString;
 transactions.Add(endString);

 return transactions;
 

If you need to send information between forms, the best thing you can do is create a property in the target form and assign the value you want to send before displaying the form; thus you will not need to change the default constructor of the form.

// Destiny form
public partial class FormDestiny : Form 
 // Property for receive data from other forms, you decide the datatype
 public string ExternalData get; set; 

 public FormDestiny() 
 InitializeComponent();
 // Set external data after InitializeComponent()
 this.MyLabel.Text = ExternalData;
 


// Source form. Here, prepare all data to send to destiny form
public partial class FormSource : Form 
 public FormSource() 
 InitializeComponent();
 

 private void SenderButton_Click(object sender, EventArgs e) 
 // Instance of destiny form
 FormDestiny destinyForm = new FormDestiny();
 destinyForm.ExternalData = PrepareExternalData("someValueIfNeeded");
 destinyForm.ShowDialog();
 

 // Your business logic here
 private string PrepareExternalData(string myparameters) 
 string result = "";
 // Some beautiful and complex code...
 return result;
