温度、湿度控件源码[原创]
上一个贴只是一个如何使用温湿度控件的一个程序例子，里面还有水印，那么可能有的朋友想知道那些控件是怎么制作的，建议有基础的可以看看控件的源码，制作控件的过程很简单很多教科书也都有说明，制作时只需要一个 pictureBox 控件即可。以下仅公布源码：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Drawing.Drawing2D;
using System.IO;
namespace AWS_CuitLu
{
public partial class UseTa : UserControl
{
private float ta = 0;//控件填充值
private float mmin = 0;//最小值控件最低点
private float mmax = 100;//最大值控件最高点
private int mfont = 8;//字体大小
Color mc = Color.Red;//颜色
private string mname = "Ta(℃)";//控件名字，您可以把它写成温度、湿度、气压、雨量、蒸发任意一个
public string Mname //控件名字属性
{
get { return (mname); }
set { mname = value; }
}
public int MFont //控件字体属性
{
get { return (mfont); }
set { mfont = value; }
}
public UseTa()
{
InitializeComponent();
}
public float Min
{
get { return (mmin); }
set { mmin = value; }
}
public float Max
{

set { mmax = value; }
}
public float TA
{
get { return (ta); }
set { ta = value; }
}

{

//记住控件是可以任意大小的，但是空间高250，宽84效果最好。
//您也可以按照高250，宽84的比例缩放效果也还可以
