Answer 1

c#里建一个Application名为：
WindowsFormsApplication1
以下两文件 对应内容粘上去覆盖原内容，运行看效果，不行将注释删了--！。
Form1.cs文件内容为。。。。
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{

if (this.colorDialog1.ShowDialog()== DialogResult.OK) {
this.textBox1.BackColor = this.colorDialog1.Color;

}

}

private void button2_Click(object sender, EventArgs e)
{
if (this.fontDialog1.ShowDialog() == DialogResult.OK)
{
this.textBox1.Font = this.fontDialog1.Font;
}

}
}
}

Form1.Designer.cs内容为。。
namespace WindowsFormsApplication1
{
partial class Form1
{
/// <summary>
/// 必要なデザイナ変数です。
/// </summary>
private System.ComponentModel.IContainer components = null;

/// <summary>
/// 使用中のリソースをすべてクリーンアップします。
/// </summary>
/// <param name="disposing">マネージ リソースが破弃される场合 true、破弃されない场合は false です。</param>
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}

#region Windows フォーム デザイナで生成されたコード

/// <summary>

private void InitializeComponent()
{
this.colorDialog1 = new System.Windows.Forms.ColorDialog();
this.fontDialog1 = new System.Windows.Forms.FontDialog();
this.button1 = new System.Windows.Forms.Button();
this.button2 = new System.Windows.Forms.Button();
this.textBox1 = new System.Windows.Forms.TextBox();
this.SuspendLayout();
//

//
this.button1.Location = new System.Drawing.Point(36, 168);
this.button1.Name = "button1";
this.button1.Size = new System.Drawing.Size(75, 23);
this.button1.TabIndex = 0;
this.button1.Text = "变背景色";
this.button1.UseVisualStyleBackColor = true;
this.button1.Click += new System.EventHandler(this.button1_Click);
//
// button2
//
this.button2.Location = new System.Drawing.Point(147, 167);
this.button2.Name = "button2";
this.button2.Size = new System.Drawing.Size(75, 23);
this.button2.TabIndex = 1;
this.button2.Text = "变字体";
this.button2.UseVisualStyleBackColor = true;
this.button2.Click += new System.EventHandler(this.button2_Click);
//
// textBox1
//
this.textBox1.Location = new System.Drawing.Point(36, 41);
this.textBox1.Multiline = true;
this.textBox1.Name = "textBox1";
this.textBox1.Size = new System.Drawing.Size(174, 83);
this.textBox1.TabIndex = 2;
this.textBox1.Text = "一二三 上山砍竹竿";
//
// Form1
//
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 12F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.ClientSize = new System.Drawing.Size(292, 266);
this.Controls.Add(this.textBox1);
this.Controls.Add(this.button2);
this.Controls.Add(this.button1);
this.Name = "Form1";
this.Text = "Form1";
this.ResumeLayout(false);
this.PerformLayout();

}
