1. 定义字典变量,并初始化
// 元素值字典 Dictionary<string, string> dic = new Dictionary<string, string>() { { "名称",""}, {"描述1",""}, {"拆分2",""} }
2.清空字典值,保留键
Dictionary<string, string>.KeyCollection keys = dic.Keys; String[] s = keys.ToArray<string>(); foreach (string a in s) { dic[a] = ""; }
不能直接用foreach循环,直接改变dic值,因为foreach是只读的。
