How Do I Split a String Into a string[]?

Question

I have a string:

string strToBeSplitted = "HelloWorld";

And I am planning to split my string to an array of string. Usually we do it with char:

char[] charReturn = strToBeSplitted.ToCharArray();

But what I am planning to do is return it with an array of string like this one:

string[] strReturn = strToBeSplitted ???
//Which contains strReturn[0] = "H"; and so on...

I want to return an array of string but I cannot figure out how to do this unless I do this manually by converting it to char then to a new string like StringBuilder.

Answer 1

You can use .Select which will iterate through each characters in the given string, and .ToString() will help you to convert a character to a string, and finally .ToArray() can help you to store the IEnumerable<string> into a string array. Hope that this is what you are looking for:

string strToBeSplitted = "HelloWorld";
string[] strArray = strToBeSplitted.Select(x => x.ToString()).ToArray();

Answer 2

您可以使用Linq快速转换它：

strToBeSplitted.Select(c => c.ToString()).ToArray();

Answer 3

为了完整性， RegEx方法分割字符：

string[] charReturn = Regex.Split("HelloWorld", "(?!^)(?<!$)");
