Look at each character in a string
提问by user1290653
I was wondering if anyone knew how to look through a string at each character and then add each character to a new string? Just a really really basic example, I can add the ToUpperand ToLowervalidation and such.
我想知道是否有人知道如何查看每个字符的字符串，然后将每个字符添加到新字符串中？只是一个非常基本的示例，我可以添加ToUpper和ToLower验证等。

string foo = "hello world", bar = string.Empty;
foreach(char c in foo){
bar += c;
}
Using StringBuilder:
使用StringBuilder：
string foo = "hello world";
StringBuilder bar = new StringBuilder();
foreach (char c in foo)
{
bar.Append(c);
}
Below is the signature of the Stringclass:
以下是 的签名Stringclass：
[SerializableAttribute]
[ComVisibleAttribute(true)]
public sealed class String : IComparable,
ICloneable, IConvertible, IComparable<string>, IEnumerable<char>,
IEnumerable, IEquatable<string>

var output = ""; // or use StringBuilder
foreach(char c in text)
{
output += c; // if or do with c what you need
}
...is that what you needed?
string is IEnumerable<char>
……这是你需要的吗？
字符串是IEnumerable<char>
