How to calculate numbers in a C#string

Question

I have a string that the Arduino sends to my application through the serial port with the following format:

variable = #value of ultrasound distance##value of ultrasound distance#...(with 10 samples equal to this one).

I need to separate only the numbers of this string, sum them together, calculate a simple average over these values stored this average in a variable and show in a textbox show the value.
If anyone can help, I’d appreciate it.

Simple.

string str = "#10##10##50##100#";

var listValores = str.Split('#').ToList();
listValores.RemoveAll(x => x == "");

decimal soma = 0;
foreach(var v in listValores)
{
    decimal vlr;
    decimal.TryParse(v, out vlr);

    soma += vlr;
}

decimal media = soma / listValores.Count;

WriteLine($"Soma: {soma} - Média: {media}");

textBox.Text = media;
