如何将单个字符转换为字符串？ [英] How do I convert a single char to a string?

问题描述

我想枚举字符串，而不是返回 chars ，我想使用迭代变量的类型为 string 。

I'd like to enumerate a string and instead of it returning chars I'd like to have the iterative variable be of type string. This probably isn't possible to have the iterative type be a string so what is the most efficient way to iterate through this string?

我是否需要在循环的每次迭代中创建一个新的 string 对象，或者我可以执行转换吗？

Do I need to create a new string object with each iteration of the loop or can I perform a cast somehow?

String myString = "Hello, World";
foreach (Char c in myString)
{
    // what I want to do in here is get a string representation of c
    // but I can't cast expression of type 'char' to type 'string'
    String cString = (String)c; // this will not compile
}

推荐答案

使用.ToString（）方法

Use the .ToString() Method

String myString = "Hello, World";
foreach (Char c in myString)
{
    String cString = c.ToString(); 
}
