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++)更多推荐
