C#计算器设计

C#计算器设计

1.掌握计算器界面设计的方法。
2.掌握和分析需求,并根据需求实现相应的功能 。
3.熟悉系统调试等相关能力,形成初步的有实用意义的计算器程序。

计算器运行结果如下:

 public static List<char> inputStr = new List<char>(1000); //用户的输入
        public Form1()

        private void btn_7_Click(object sender, EventArgs e)

        }

        private void btn_Rig_Click(object sender, EventArgs e)
        {
     
            inputStr.Add(')');

            richTextBox1.AppendText(")");

        }

        private void btn_Equal_Click(object sender, EventArgs e)
        {
     
            //等号代码

            richTextBox1.AppendText("=");

            richTextBox1.Text = richTextBox1.Text;

            richTextBox1.Text = DataOp.DataMain();

            string temp = DataOp.DataMain();

            inputStr.Clear();

            for (int i = 0; i < temp.Length; i++)
            {
     

                inputStr.Add(temp[i]);

            }

        }

        private void btn_Add_Click(object sender, EventArgs e)
        {
     
            inputStr.Add('+');

            richTextBox1.AppendText("+");

        }

        private void btn_Subt_Click(object sender, EventArgs e)
        {
     
            inputStr.Add('-');
            richTextBox1.AppendText("-");
        }
        private void btn_Mul_Click(object sender, EventArgs e)
        {
     
            inputStr.Add('×');
            richTextBox1.AppendText("×");
        }
        private void btn_Divi_Click(object sender, EventArgs e)
        {
     
            inputStr.Add('÷');
            richTextBox1.AppendText("÷");
        }
        private void btn_Ce_Click(object sender, EventArgs e)
        {
     
            richTextBox1.Text = "";
            inputStr.Clear(); //清空链表的所有元素
        }
        private void btn_C_Click(object sender, EventArgs e)
        {
     
            //界面撤销
            inputStr.RemoveAt(inputStr.Count - 1);
            richTextBox1.Text = "";
            for (int i = 0; i < inputStr.Count; i++)
            {
     
                richTextBox1.Text += inputStr[i];
            }
        }

美化设计主要是计算器背景优化和控件的透明度。使控件透明来陪衬背景,以此增加视觉效果,变得更美观。
而透明度更改只需更改控件属性即可,例如btn_1:

 this.btn_1.BackColor = System.Drawing.Color.Transparent;
            this.btn_1.FlatAppearance.BorderSize = 0;
            this.btn_1.FlatStyle = System.Windows.Forms.FlatStyle.Flat;
            this.btn_1.Font = new System.Drawing.Font("仿宋", 15.75F, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, ((byte)(134)));
            this.btn_1.ForeColor = System.Drawing.SystemColors.ButtonHighlight;
            this.btn_1.Location = new System.Drawing.Point(16, 239);
            this.btn_1.Margin = new System.Windows.Forms.Padding(4);
            this.btn_1.Name = "btn_1";
            this.btn_1.Size = new System.Drawing.Size(83, 45);
            this.btn_1.TabIndex = 11;
            this.btn_1.Text = "1";
            this.btn_1.UseVisualStyleBackColor = false;
            this.btn_1.Click += new System.EventHandler(this.btn_1_Click);

0-9数字由button控件控制运行,0-9数字的设计代码:

 private void btn_0_Click(object sender, EventArgs e)
        {
     

            inputStr.Add('0');

            richTextBox1.AppendText("0"); 
        
//1-9的代码以此类推 
//显示屏由控件richTextBox构成。
//运算符号包括:+-/*和()运算符号代码:
        private void btn_Left_Click(object sender, EventArgs e)
        {
     
            inputStr.Add('(');

            richTextBox1.AppendText("(");

        }

        private void btn_Rig_Click(object sender, EventArgs e)
        {
     
            inputStr.Add(')');

            richTextBox1.AppendText(")");

        }

        private void btn_Equal_Click(object sender, EventArgs e)
        {
     
            //等号代码

            richTextBox1.AppendText("=");

            richTextBox1.Text = richTextBox1.Text;

            richTextBox1.Text = DataOp.DataMain();

            string temp = DataOp.DataMain();

            inputStr.Clear();

            for (int i = 0; i < temp.Length; i++)
            {
     

                inputStr.Add(temp[i]);

            }

        }

        private void btn_Add_Click(object sender, EventArgs e)
        {
     
            inputStr.Add('+');

            richTextBox1.AppendText("+");

        }

        private void btn_Subt_Click(object sender, EventArgs e)
        {
     
            inputStr.Add('-');
            richTextBox1.AppendText("-");
        }
        private void btn_Mul_Click(object sender, EventArgs e)
        {
     
            inputStr.Add('×');
            richTextBox1.AppendText("×");
        }
        private void btn_Divi_Click(object sender, EventArgs e)
        {
     
            inputStr.Add('÷');
            richTextBox1.AppendText("÷");
        }
//界面的清空和撤销:
 private void btn_Ce_Click(object sender, EventArgs e)
        {
     
            richTextBox1.Text = "";
            inputStr.Clear(); //清空链表的所有元素
        }
        private void btn_C_Click(object sender, EventArgs e)
        {
     
            //界面撤销
            inputStr.RemoveAt(inputStr.Count - 1);
            richTextBox1.Text = "";
            for (int i = 0; i < inputStr.Count; i++)
            {
     
                richTextBox1.Text += inputStr[i];
            }
        }
