C#常用代码

List 操作

取出list其中对象的属性值，还可以做去重复点的操作

int cnt = list.Select(r => r.point).Distinct().Count();

字符串格式化

string line = string.Format("{0:0.00} {1:0.00} {2:0.00000}", x, y, p.val);

字典定义和遍历

// 定义待转换的 dir 路径 和 线号
Dictionary<string, int> dict = new Dictionary<string, int>()
{
    {
        @"D:\AAA\-10m极距\L1",
        1
    },
    {
        @"D:\AAA\-10m极距\L2",
        2
    },
    {
        @"D:\AAA\-10m极距\L3",
        3
    },
    {
        @"D:\AAA\-10m极距\L4",
        4
    },
    {
        @"D:\AAA\L4-5m极距\L4_电场",
        4
    },
    {
        @"D:\AAA\L4-0.5m极距\L4-0.5",
        4
    }
};

foreach (KeyValuePair<string, int> kvp in dict)
{
    string dir = kvp.Key;
    int lineNo = kvp.Value;

    dmCalculateAndMergeFile(dir, lineNo);

    string msg = "目录：" + dir + "线号：" + lineNo + "，转换成功！";
    Console.WriteLine(msg);
}
