从C#windows窗体应用程序图计算值
我正在进行热测试，其中有3个设定值（带+/1C）需要确认。 设定点为从C#windows窗体应用程序图计算值,c#,.net,winforms,math,statistics,C#,.net,Winforms,Math,Statistics,我正在进行热测试，其中有3个设定值（带+/1C）需要确认。 设定点为 37C 60摄氏度 80摄氏度 我已经创建了一个Windows窗体应用程序，可以从“CSV”文件上载数据并在应用程序上打印。 如何计算每个设定点范围的平均值、最小值和最大值？ （标记的红色框不是来自应用程序） 是否有方法确定每个设定点的中心点，并在中间两侧2.5分钟之间进行计算 CSV数据如下所示 任何有助于我朝正确方向发展的意见都将不胜感激 很抱歉回复太晚。 我已经用代码和CSV数据链接更新了问题 using Syste
