Hi CemYedikardes-5780,

Welcome to our Microsoft Q&A platform!

There is no such property or method to set x:Name for Xamarin controls. In essence, x:Name is only used to help the compiler recognize the control.

If you want to identify a control programmatically, you can use the property StyleId. According to documentation:Element.StyleId Property, we know that it can be used to set a user defined value to uniquely identify the element.

for (int i = 0; i < 2; i++)  
{  
    Entry aentry = new Entry  
    {  
        StyleId = $"Entry{i}",  
    };  
    stack.Children.Add(aentry);  
};

Then you can use the following code to get the specified control based on the StyleId.

var theEntry = stack.Children.ToList().Find(item => item.StyleId == "Entry1");  
Console.WriteLine((theEntry as Entry).Text);

Regards,
Kyle

orry I am beginer level :( and didnt understand below part.

var theEntry = stack.Children.ToList().Find(item => item.StyleId == "Entry1");

Console.WriteLine((theEntry as Entry).Text);

I tried like below but it is not working:(.

Double A, B, C; for (int i = 0; i < 2; i++)

{
Entry aentry = new Entry
{
StyleId = $"Entry{i}",
};
stack.Children.Add(aentry);
};

A = Convert.ToDouble(Entry0.Text); B = Convert.ToDouble(Entry1.Text); C = A + B; Entry2.Text + = C;

@Cem Yedikardes For method "Find", you can refer to document List<T>.Find(Predicate<T>) Method. In this method, we use anonymous function as its parameter. And here is the document of anonymous function: Anonymous functions (C# Programming Guide).
It is equivalent to the following code.

foreach (var item in stack.Children) { if (item.StyleId == "Entry1") { Console.WriteLine((item as Entry).Text); return; } }

It seems that you want to create three Entries, but your for statement only loops twice. The for statement should be modified as follows.

for (int i = 0; i < 3; i++) { //... };

Besides, if you want to display the result of the summation of Entry0 and Entry1 in Entry2, you should assign a value to Entry2's Text directly, rather than using "+=".

Entry2.Text = C.ToString();
