Solution 1

string a = textbox.text;  // hello-1234G
string b = string.Join("", input.Where(k => char.IsNumber(k)));  // 1234

Oh, its working, thank you
if may I ask another question, I want to fetch data from database which also has the same format so I want to check the numeric value just for example:
the database table:
Id name
000001 Hello-1234g
000002 Hello-1235g

so if I enter in textbox the value of :hello-1235g
I want to import the first row just.
