C＃循環

Question

我有隨機數發生器

Random random = new Random(); 
    int x = random.Next(25); 

和

List<int> mylist = new List<int>() {1,2,3,4,5,6,7}

所以我怎麼能遍歷列表，如果隨機數是在列表中，他們把這個數字將文本框或標籤？

Answer 1

//Loop through each int in the list 
foreach (int i in myList) 
{ 
    //If the current int (i) equals the random (x)... 
    if (i == x) 
    { 
     //Set it as the TextBox text (substitute out "someTextBox" for your TextBox or Label 
     someTextBox.Text = i.ToString(); 
    } 
}
