如何使用字符串分隔符拆分字符串？

Question

How can I split a string using a string delimeter?

I've tried:

string[] htmlItems = correctHtml.Split("<tr");

I get the error:

Cannot convert from 'string' to 'char[]'

What's the recommended way to split a string on a given string parameter?

Answer 1

There is a version of string.Split that takes a string array and an options parameter:

string source = "[stop]ONE[stop][stop]TWO[stop][stop][stop]THREE[stop][stop]";
string[] stringSeparators = new string[] {"[stop]"};
string[] result = source.Split(stringSeparators, StringSplitOptions.None);

so even though you only have one separator you want to split on you still have to pass it as an array.

Taking Mike Hofer's answer as a starting point, this extension method will make it a bit simpler to use.

public static string[] Split(this string value, string separator)
{
    return value.Split(new string[] {separator}, StringSplitOptions.None);
}

Have a look at Regex.Split

Answer 3

Isn't this the overload you are searching for? http://msdn.microsoft.com/en-us/library/1bwe3zdy.aspx

Answer 4

您还需要在Split中使用StringSplitOptions参数。

Answer 5

Write an extension method:

public static string[] Split(this string value, string separator)
{
    return value.Split(separator.ToCharArray());
}

Problem solved.
