我只想将所有这些查询作为一个查询运行。
string[] arrs = new string[] { ".sds", ".pps", "tbt", "dd." };
string[] val= (from string i in arrs
where !i.StartsWith(".")
select "."+i).ToArray();
string[] val1 = (from i in arrs
where i.StartsWith(".")
select i).ToArray();
var p = val1.Union(val);//get value in single array.e
最佳答案
var p = (from s in arrs
select s.StartsWith(".") ? s : "." + s).ToArray();
或非查询语法:
var p = arrs.Select(s => s.StartsWith(".") ? s : "." + s)
.ToArray();
并且您不希望像
.Distinct()
一样重复{ "foo", ".foo" }
。var p = arrs.Select(s => s.StartsWith(".") ? s : "." + s)
.Distinct()
.ToArray();
