有人检查这个并告诉我在课堂上获取价值的方法吗？

本文介绍了有人检查这个并告诉我在课堂上获取价值的方法吗？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 有人告诉我将按钮点击事件的价值传递给上课 public partial class 登录：System.Web.UI.Page { protected void Page_Load（ object sender，EventArgs e） {} public void Button1_Click（ object sender，EventArgs e） { String End_Address = TextBox2.Text; //我将文本框值传递给字符串...在c＃ 所以我想访问类文件中的字符串.... public class harversine {登录实例= 新登录（）; 字符串 valueEnd_Address = instance.End_Address; 这是否正确？解决方案 你可以这样做： public partial class 登录：System.Web.UI.Page { public String End_Address = string .Empty; 受保护 void Page_Load（对象发​​件人，EventArgs e） {} public void Button1_Click（ object sender，EventArgs e） { End_Address = TextBox2.Text; 然后访问它完全使用你所写的内容。 逻辑上它正确但你会不获取信息，因为实例将是一个不同的对象，而不是与客户端呈现的相同。相反，您可以尝试以下选项之一。 1.将end_address作为参数传递给构造函数以使用harversine类。 ex：在后面的登录代码中，harversine inst = new harversine（TextBox2.Text）; 2.在harversine类中声明属性EndAddress并分配vlaue点击事件背后的代码 ex： harversine inst = new harversine（）; inst.EndAddress = TextBox2.Text; 您可以使用 C＃中的属性 [ ^ ]。 在 harversine 类中声明属性。 private string _End_Address; public string End_Address { get { return _End_Address; } set {_End_Address = value ; } } 从登录页面设置。请参阅： public void Button1_Click （ object sender，EventArgs e） { harversine obj = new harversine（ ）; obj.End_Address = TextBox2.Text; } 您可以在 harversine 类中访问它： public void SomeFunction（） { if （End_Address！= null ） string EndAdd = End_Address; } 有关详细信息，请参阅以下链接： C＃Property [ ^ ] - Amit someone tell me way to pass the value of button click event to classpublic partial class Login : System.Web.UI.Page{ protected void Page_Load(object sender, EventArgs e) { } public void Button1_Click(object sender, EventArgs e) { String End_Address = TextBox2.Text; // i'm passing textbox value into string... in c#so i want to access the string in class file....public class harversine { Login instance = new Login(); String valueEnd_Address = instance.End_Address;is this correct or not? 解决方案 You could do this:public partial class Login : System.Web.UI.Page{ public String End_Address = string.Empty; protected void Page_Load(object sender, EventArgs e) { } public void Button1_Click(object sender, EventArgs e) { End_Address = TextBox2.Text; Then to access it use exactly what you wrote.Logically its correct but you will not get info as instance will be a differnt object and not the same what is rendered to the client. Instead you can try one of the following options.1. Pass end_address as a paramater to the constructor to harversine class. ex: In login code behind harversine inst = new harversine(TextBox2.Text);2. Declare a property EndAddress in harversine class and assign the vlaue in code behind click event ex: harversine inst = new harversine(); inst.EndAddress =TextBox2.Text; You can easily do it using Properties in C#[^].Declare a Property in harversine class. private string _End_Address;public string End_Address{ get { return _End_Address; } set { _End_Address = value; }}Set it from login page. See this:public void Button1_Click(object sender, EventArgs e){ harversine obj = new harversine(); obj.End_Address = TextBox2.Text;}You can access it in your harversine class:public void SomeFunction(){ if(End_Address != null) string EndAdd = End_Address;}Refer the below link for more details:C# Property[^]--Amit 这篇关于有人检查这个并告诉我在课堂上获取价值的方法吗？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
