如何在运行时在WinForm中添加按钮？

Question

我有以下代码:

public GUIWevbDav()
{
    InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{
    try
    {
        //My XML Loading and other Code Here

        //Trying to add Buttons here
        if (DisplayNameNodes.Count > 0)
        {
            for (int i = 0; i < DisplayNameNodes.Count; i++)
            {
                Button folderButton = new Button();
                folderButton.Width = 150;
                folderButton.Height = 70;
                folderButton.ForeColor = Color.Black;
                folderButton.Text = DisplayNameNodes[i].InnerText;

                Now trying to do  GUIWevbDav.Controls.Add
                (unable to get GUIWevbDav.Controls method )

            }
        }

我不想在运行时创建一个表单,但是将动态创建的按钮添加到Current Winform即:GUIWevDav

谢谢

Answer 1

只是用this.Controls.Add(folderButton).this是你的形式.

Answer 2

您的代码中的问题是您正在尝试调用表单类型的Controls.Add()方法,GUIWevbDav并且您无法在类型上获取Control.Add,它不是静态方法.它只适用于实例.

for (int i = 0; i < DisplayNameNodes.Count; i++) 
{ 

    Button folderButton = new Button(); 
    folderButton.Width = 150; 
    folderButton.Height = 70; 
    folderButton.ForeColor = Color.Black; 
    folderButton.Text = DisplayNameNodes[i].InnerText; 

    //This will work and add button to your Form.
    this.Controls.Add(folderButton );

    //you can't get Control.Add on a type, it's not a static method. It only works on instances.
    //GUIWevbDav.Controls.Add

}
