在C#中动态添加控件到循环下

本文介绍了在C#中动态添加控件到循环下的处理方法，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

我正在开发Windows应用程序，我想在其中循环动态创建一些控件. 我正在尝试的代码是

I am developing a windows application where I want to create some controls dynamically inside a loop. The code I am trying is

private Label newLabel = new Label(); private int txtBoxStartPosition = 100; private int txtBoxStartPositionV = 25; for (int i = 0; i < 7; i++) { newLabel.Location = new System.Drawing.Point(txtBoxStartPosition, txtBoxStartPositionV); newLabel.Size = new System.Drawing.Size(70, 40); newLabel.Text = i.ToString(); panel1.Controls.Add(newLabel); txtBoxStartPositionV += 30; }

此代码仅生成一个带有文本7的标签，但是我想用它们各自的文本创建8个标签，我该怎么做?

This code is generating only one Label with text 7 but I want to create 8 Lables with their respective texts, how can I do this?

推荐答案

在您的循环中，您实质上是在更新同一Label的属性.如果要在每个步骤上创建一个新对象，请在循环内移动对象的创建:

In your loop you are essentially updating properties of the very same Label. If you want create a new one on each step, move creation of the object inside the loop:

private Label newLabel; for (int i = 0; i < 7; i++) { newLabel = new Label(); ...

如果想要 8 标签，您的for应该迭代8次，而不是7次，就像现在这样:

By the way if you want 8 labels - your for should iterate 8 times, not 7, as it does now:

for (int i = 0; i < 8; i++)
