我有一个非常简单的Iron Python / Windows Form应用程序。当应用程序启动时，它会在数组中添加一系列标签（这是从CSV文件开始）

＆＃13;
＆＃13; 
#Create Label for each Site
for s in sites:
    
    if lasty == 682:
        lasty = 0
        lastx = lastx + 125

    sitename = str(s) #Convert Name into a String
    elementname = sitename.replace(" ","") + "Label"
    element = Label()
    element.Name = elementname
    element.Text = str(sitename)
    element.Parent = self
    element.Location = Point(lastx,lasty)

    labels.append(element) #add each element to the list

    lasty = lasty + 22
    pass
＆＃13;
＆＃13;
＆＃13;

这很好用。然后我有一个运行另一个循环的定义，根据结果我希望它改变标签的颜色。让我们说Red为失败，Green为OK，Yellow为警告。

但是我似乎无法通过我给他们的元素名称链接到这些标签

例如，我认为SiteNameLabel.ForeColor = Color.Green会将该标签变为绿色。但是这会失败并停止程序。

有什么想法吗？最有可能是一个简单的问题，但我无法在网上找到任何相关信息。

这是错误：

您不能使用 SiteNameLabel 作为对象参考。您必须从表单的Controls集合中获取Label的引用。请参阅以下代码：

import clr
clr.AddReference('System.Drawing')
clr.AddReference('System.Windows.Forms')

from System.Drawing import *
from System.Windows.Forms import *

class MyForm(Form):
    def __init__(self):
        myLabel = Label()
        myLabel.Location = Point(10, 10)
        myLabel.Text = "EXAMPLE LABEL"
        myLabel.Name = "myLabel"
        self.Controls.Add(myLabel)

        # later you can find label by name this way:
        self.Controls["myLabel"].ForeColor = Color.Green

Application.EnableVisualStyles()
Application.SetCompatibleTextRenderingDefault(False)

form = MyForm()
Application.Run(form)

注意：当您使用WinForms设计器时（在C＃项目示例中），它会生成具有控件名称的表单成员，因此您可以在尝试时访问它们。但这仅适用于在设计时添加的控件。
