无法从&#39;System.Collections.Generic.IEnumerable转换 <char> &#39;到&#39;字符串&#39;

Question

I try to Reverse my string but I get to following error

string str = word.Reverse();

error:

cannot convert from 'System.Collections.Generic.IEnumerable' to 'string'

anyone know what should I need to do ?

Answer 1

You should build a new string.

string str = new string(word.Reverse().ToArray());

Calling ToArray() on an IEnumerable<T> will convert it to T[] .

string has a constructor which get array of character and constructs a string.

Answer 2

您应该将字符连接在一起以创建新字符串。

string str = string.Join(string.Empty, word.Reverse());
