As other’s have mentioned, this isn’t very clear. Although I think I understand your issue, I can’t relate it to the context without an example of what you’ve tried already.<\/p>\n

Anyway, you can use regex for this.<\/p>\n

using System.Text.RegularExpressions;\n<\/code><\/pre>\n
Then, assuming you’ve stored the input as a variable, let’s say “userInput”<\/p>\n
Convert.ToInt32(Regex.Replace(userInput, \"[^0-9]+\", string.Empty));\n<\/code><\/pre>\n
This will return a integer of the extracted numbers. I’ll update my answer once you’ve updated your question.<\/p>\n
EDIT: Literally as soon as I posted this you updated it. My above code will still work, if you assign textBox1.Text to a variable.<\/p>\n
    private void button1_MouseClick(object sender, MouseEventArgs e)\n    {\n        string userInput = textBox1.Text;\n        int sum = 0;\n        if (IsAllLetters(userInput) == true)\n        {\n            for (int i = 0; i < userInput.Length; i++)\n            {\n                sum += (int)char.GetNumericValue(userInput[i]);\n            }\n            label2.Text = \"Summa:               \" + sum;\n        }\n        else\n        {\n            DialogResult dialogResult = MessageBox.Show(\"Delete all letters??\", \"Alert\", MessageBoxButtons.YesNo);\n            if (dialogResult == DialogResult.Yes)\n            {\n                userInput = Regex.Replace(userInput, \"[^0-9]+\", string.Empty);\n                for (int i = 0; i < userInput.Length; i++)\n                {\n                    sum += (int)char.GetNumericValue(userInput[i]);\n                }\n                label2.Text = \"Summa:               \" + sum;\n            }\n            else if (dialogResult == DialogResult.No)\n            {\n                \/\/do something else\n            }\n        }\n\n    }\n    public static bool IsAllLetters(string s)\n    {\n        foreach (char c in s)\n        {\n            if (Char.IsLetter(c))\n                return false;\n        }\n        return true;\n    }\n<\/code><\/pre>\n<\/p><\/div>\n
