C＃Windows窗体类型转换错误

Question

Right now, I am learning C# from a textbook. In one of the examples in the chapter I'm currently stuck on, Windows Forms, I am instructed to enter the following code to create a simple window:

namespace WinForms {

using System;
using System.Drawing;
using System.ComponentModel;
using System.Windows.Forms;

public class HelloWindowsForms : System.Windows.Forms.Form
{
    private System.Windows.Forms.Label label1;

    public HelloWindowsForms()
    {
        this.label1 = new System.Windows.Forms.Label();

        label1.Location = new System.Drawing.Point(8,8);
        label1.Text = "Hello Windows Forms!";
        label1.Size = new System.Drawing.Size(408,48);
        label1.Font = new System.Drawing.Font("Microsoft Sans Serif", 24f);
        label1.TabIndex = 0;
        label1.TextAlign = System.Windows.Forms.HorizontalAlignment.Center; //this is the problem

        this.Text = "Hello World";
        this.MaximizeBox = false;
        this.AutoScaleBaseSize = new System.Drawing.Size(5,13);
        this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedDialog;
        this.MinimizeBox = false;
        this.ClientSize = new System.Drawing.Size(426,55);
        this.Controls.Add(label1);
    }

    public static void Main(string[] args)
    {
        Application.Run(new HelloWindowsForms());
    }
    }
}

On the problem line(specified in single line comment) I get this error when running this program:

Cannot implicitly convert type 'System.Windows.Forms.HorizontalAlignment' to 'System.Drawing.ContentAlignment'. An explicit conversion exists (are you missing a cast?) (CS0266)

Other sources online say I need to cast, but I can't figure out what to cast or what to cast it as. I tried skipping ahead and completing the chapter, but I get similar Cannot implicitly convert type errors when trying to do all of the examples. Can someone help me figure out how to fix this?

Answer 1

You are using the wrong enum. You are using a System.Windows.Forms.HorizontalAlignment enum when the TextAlign property is calling for a System.Drawing.ContentAlignment enum. Try this:

label1.TextAlign = System.Drawing.ContentAlignment.MiddleCenter;

Answer 2

I bumped in the same problem and figured this out,

If you are using

Label

then use this:

this.Label1.TextAlign = System.Drawing.ContentAlignment.MiddleCenter;

I think you are using

TextBox

Therefore, use:

this.textbox1.TextAlign = System.Windows.Forms.HorizontalAlignment.Center;
