您能给我一个文本框示例代码吗? C# [英] Can you give me a sample code for textbox? c#

问题描述

如果来自frmPayment.cs的txtTotal.Text等于位于frmSalesOrder.cs的txtSalesOrderTotal.Text，我想在位于(frmSalesOrder.cs)的txtOrderStatus.Text下创建条件以指示已付款"

frmSalesOrder.cs
txtOrderStatus.Text --->表示已付费"
txtSalesOrderTotal.Text


frmPayment.cs
txtTotal.Text

I want to create a condition under txtOrderStatus.Text located at(frmSalesOrder.cs) to indicate "Paid" if txtTotal.Text from frmPayment.cs is equal to txtSalesOrderTotal.Text located at frmSalesOrder.cs


frmSalesOrder.cs
txtOrderStatus.Text ---> indicate "Paid"
txtSalesOrderTotal.Text


frmPayment.cs
txtTotal.Text

推荐答案

frmSalesOrder
---------------
公开您的 frmSalesOrder 类.

创建一个将保留您的总计值的属性；

frmSalesOrder
---------------
Make your frmSalesOrder class public.

Create a property that will hold your Total value;

public string Total { get; set; }

然后，在将转移到frmSalesOrder的按钮单击事件上，设置该属性.

Then on your button click event that will transfer to frmSalesOrder, set that property.

Total = txtTotal.Text;

frmSalesOrder
---------------

然后，您现在可以从此处访问总计.

frmSalesOrder
---------------

Then you can now access the Total from here.

txtOrderStatus.Text = frmSalesOrder.Total == txtSalesOrderTotal.Text ? "Paid" : "Not Paid";

If it is web application

由于我们的文本框位于不同的页面上，因此您可以将两个值都存储在会话中，并且可以进行比较.

session ["Total"] = txtTotal.text;
session ["sales"] = txtsalesorder.text;

在页面上您想比较，您可以像

if(session ["Total"].tostring()== session ["sales"].tostring())
txtorderstatus.text = paid;

as ur textboxes are on differnt page , u can store both values in session and can compare like.

session["Total"]=txtTotal.text;
session["sales"]=txtsalesorder.text;

on the page u want to compare u can do like

if(session["Total"].tostring()==session["sales"].tostring())
txtorderstatus.text=paid;

If it is windows 

ucan将textboxvalue存储在类似
的字符串中

ucan store textboxvalue in string like

string Total=txtTotal.text;

在其他页面上，您可以像

on other page u can retreive like

Form1.Total
