输出字符串格式化/ Linq对数组操作 /一个按钮样式

          textBox1.Text = dateTimePicker1.Value.ToString("yyyy-MM-dd HH:mm:ss");

 

            int[] arr = { 100, 20, 2, 4, 104, 1, 21, 101, 102, 201, 202 };
            var data = arr.Where(n => n % 2 == 0 && n > 100).OrderByDescending(n => n);
            foreach (var x in data) {
                Console.WriteLine(x);
            }
            Console.ReadKey();

 

           // 
            // button1
            // 
            this.button1.BackColor = System.Drawing.SystemColors.Window;//背景色
            this.button1.FlatAppearance.BorderColor = System.Drawing.Color.FromArgb(((int)(((byte)(128)))), ((int)(((byte)(128)))), ((int)(((byte)(255)))));//边框颜色
            this.button1.FlatAppearance.BorderSize = 2;//边框大小
            this.button1.FlatAppearance.MouseDownBackColor = System.Drawing.Color.Blue;//鼠标按下背景
            this.button1.FlatAppearance.MouseOverBackColor = System.Drawing.Color.FromArgb(((int)(((byte)(128)))), ((int)(((byte)(128)))), ((int)(((byte)(255)))));//鼠标停留背景色
            this.button1.FlatStyle = System.Windows.Forms.FlatStyle.Flat;//平面样式
            this.button1.Font = new System.Drawing.Font("微软雅黑", 12F, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, ((byte)(0)));//字体
            this.button1.Location = new System.Drawing.Point(53, 64);//位置
            this.button1.Name = "button1"; //设计名字
            this.button1.Size = new System.Drawing.Size(130, 34); //大小
            this.button1.TabIndex = 4; //索引 tab键 
            this.button1.Text = "登录"; //显示名称
            this.button1.UseVisualStyleBackColor = false; //使用视觉样式背景色 默认
