WPF For循环和For循环 [英] WPF For loop and For each loop

问题描述

我正在使用WPF，我遇到了for循环和每个循环的问题。

 For（int I = 0; I< 10; i ++）
 
 {
 
 TextBox1.Text = I.ToString（）
 
} 

 string [] A = {" A"，" B"，" C"，" D" }; 
 
 for（int i = 0; i< 2; i ++）
 {
 
 textBox2.Text = A [i] .ToString（）; 
} 

这个有效，但我认为他们是一种使用for循环做同样事情的方法。 for循环和每个循环的任何示例都有帮助谢谢

 var result = Enumerable.Range（0,10）.Select（i => i.ToString（ ））。Aggregate（（init，next）=> init + Environment.NewLine + next）; 
 textBox1.Text = result; 

解决方案

而不是你的Enumerable.Range ...你可以使用这个循环：

 string result = string.Empty; 
 for（int i = 0; i< 10; i ++）result + =（string.IsNullOrEmpty（result））？

" {i}" ：

" {Environment.NewLine} {I}英寸;
TextBox3.Text = result;

I am working with WPF and I am having issues with for loop and for each loops.

For(int I = 0; I < 10; i++)

{

TextBox1.Text = I.ToString()

}

string[] A = { "A", "B", "C", "D" };

            for (int i = 0; i < 2; i++)
            {

               textBox2.Text = A[i].ToString();
            }

This one works but i would think their is a way to uses a for loop to do the same thing as this. Any examples of for loops and for each loops would help thanks

 var result = Enumerable.Range(0, 10).Select(i => i.ToString()).Aggregate((init, next) => init + Environment.NewLine + next);
            textBox1.Text = result;

解决方案

Hi,
instead of yours Enumerable.Range… you can use this loop:

        string result = string.Empty;
        for (int i = 0; i < 10; i++) result += (string.IsNullOrEmpty(result)) ?

"{i}" :

"{Environment.NewLine}{i}"; TextBox3.Text = result;
