当按钮多次点击C＃改变标签文本 [英] C# change label text when button clicked multiple times

问题描述

对不起，我是新来这个只是想知道，如果有人可以帮助，我试图让我的标签，我点击按钮，每一次改变其文本。不知道我应该怎么去做。谁能帮我请。

 私人无效的button1_Click（对象发件人，EventArgs五）
 {
串[] MONTHNAME; 
 MONTHNAME =新的字符串[12]; 
 
 MONTHNAME [0] =一月; 
 MONTHNAME [1] =二月; 
 MONTHNAME [2] =三八; 
 MONTHNAME [3] =四月; 
 MONTHNAME [4] =五一 
 MONTHNAME [5] =六一; 
 MONTHNAME [6] =七一; 
 MONTHNAME [7] =八一; 
 MONTHNAME [8] =九; 
 MONTHNAME [9] =十一; 
 MONTHNAME [10] =十一月; 
 MONTHNAME [11] =十二月; 
 
 
 label1.Text =（MONTHNAME [0]）; 
 label1.Text =（MONTHNAME [1]）; 
  

解决方案

这应该做的伎俩：

声明在类中的数组和int

 的String [] MONTHNAME = {一月，二月，月，月，月，君，月，月，月，月，月，月}; 
静态INT I = 0; 
  

然后在点击按钮

 保护无效btnAddMonth_Click（对象发件人，EventArgs五）
 {
 lblMonth.Text = MONTHNAME [I] 
 I =（I + 1）％12; 
} 
  

Sorry I am new to this just wondering if someone can help, I am trying to get my label to change its text every time I click the button. Not sure how I should go about it. Can anyone help me please.

private void button1_Click(object sender, EventArgs e)
    {  
        string[] MonthName;
        MonthName = new string[12];

        MonthName[0] = "January";
        MonthName[1] = "February";
        MonthName[2] = "March";
        MonthName[3] = "April";
        MonthName[4] = "May";
        MonthName[5] = "June";
        MonthName[6] = "July";
        MonthName[7] = "August";
        MonthName[8] = "September";
        MonthName[9] = "October";
        MonthName[10] = "November";
        MonthName[11] = "December";


            label1.Text = (MonthName[0]);
            label1.Text = (MonthName[1]);   

解决方案

This should do the trick:

Declare the array and an int in the class

string[] MonthName = { "Jan", "Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec" };
    static int i = 0;

Then in the button click

protected void btnAddMonth_Click(object sender, EventArgs e)
{
    lblMonth.Text = MonthName[i];
    i = (i+1) % 12;
}
