方法来创建和更改标签

Question

我想创建标签和使用方法设置文本，但它不会工作，这是我的代码：

public partial class Form1 : Form 
{   
    public Form1() 
    {    
     InitializeComponent(); 
     intro(); 
    } 
    private void fullScreen() 
    { 
     this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None; 
     this.Bounds = Screen.PrimaryScreen.Bounds; 
    } 
    private void intro() 
    { 
     pictureBox1.BackColor = Color.White; 
     pictureBox1.SendToBack(); 
     Label introInfo = new Label(); 
     introInfo.Font = new Font("century gothic", 24, FontStyle.Bold); 
     introInfo.ForeColor = Color.Cyan; 
     introInfo.Text = "succes bro!"; 
     introInfo.Visible = true; 
     introInfo.Location = new Point(100, 100);    
    }   
} 

我应该怎么做，使其工作？

Answer 1

您需要将label添加到form

this.Controls.Add(label); 

看看this example

public partial class Form1 : Form 
{ 
    public Form1() 
    { 
     InitializeComponent(); 
     this.Load += Form1_Load; 
    } 

    void Form1_Load(object sender, EventArgs e) 
    { 
     intro(); 
    } 

    private void fullScreen() 
    { 
     this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None; 
     this.Bounds = Screen.PrimaryScreen.Bounds; 
    } 

    private void intro() 
    { 
     Label introInfo = new Label(); 
     introInfo.Font = new Font("century gothic", 24, FontStyle.Bold); 
     introInfo.ForeColor = Color.Cyan; 
     introInfo.Text = "succes bro!"; 
     introInfo.Visible = true; 
     introInfo.Location = new Point(100, 100); 
     introInfo.Height = 35; 
     introInfo.Width = 250; 

     this.Controls.Add(introInfo); 
    } 
}

你需要新创建的标签添加到控件集合

public partial class Form1 : Form 
{   
    public Form1() 
    {    
     InitializeComponent(); 
     intro(); 
    } 
    private void fullScreen() 
    { 
     this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None; 
     this.Bounds = Screen.PrimaryScreen.Bounds; 
    } 


    private void intro() 
    { 
     pictureBox1.BackColor = Color.White; 
     pictureBox1.SendToBack(); 
     Label introInfo = new Label(); 
     introInfo.Font = new Font("century gothic", 12, FontStyle.Bold); 
     introInfo.ForeColor = Color.Cyan; 
     introInfo.Text = "succes bro!"; 
     introInfo.Visible = true; 
     introInfo.Location = new Point(75, 23); 
     introInfo.Size= new Size(100,100); 
     this.Controls.Add(introInfo); 
    }
