记号化字符串与字符串DELIM [英] Tokenize a string with delim of strings

问题描述

如果我有这样一个字符串

  

这是将由此而被拆分一个字符串

我想获得分割结果

1. 是将由被分割的字符串


2. 和


3. 这是一个字符串


4. 将由此分裂和

1和2分别由这个分割
图3和4是由分割，即

我的解决方法是使用地图一串字符串，并将结果存储在同一类型串来串的另一个地图。然而，对于更复杂和更长的文字，其结果存储在地图成为在上述1和3的子串重复，即为是一个字符串被重复并且这个冗余产生不正确的统计结果。

请您提供一个整洁的更好的解决方案，以标记化的长字符串与不同的长字符串分隔符？

解决方案

 字符串的myString =这是将由此而被分裂一个字符串;
串富= myString.ToUpper（）;字符串[] = byThis foo.Split（新的String [] {这个}，StringSplitOptions.RemoveEmptyEntries）;
字符串[] = byThat foo.Split（新的String [] {，即}，StringSplitOptions.RemoveEmptyEntries）;字符串[] =所有foo.Split（新的String [] {表示，这个}，StringSplitOptions.RemoveEmptyEntries）;
 

或者你可以使用正则表达式为

 的String [] =所有System.Text.RegularEx pressions.Regex.Split（MyString的，你的模式，System.Text.RegularEx pressions.RegexOptions。 IGNORECASE）;
 

If I have a string like

"This is a string that will be split by this and that"

I would like to get the split results as

1. "is a string that will be split by"
2. "and that"
3. "this is a string"
4. "will be split by this and"

1 and 2 are split by "this" 3 and 4 are split by "that"

My solution is use a map of string to string and store the result in another map of the same type-string to string. However, for more complex and longer text, the results stored in the map become repeated, i.e as in the above 1 and 3 the substring "is a string" is repeated and this redundancy produces incorrect statistical results.

Would you please offer a neat better solution to tokenizing a long string with delimiters that are different long strings?

解决方案

string myString = "This is a string that will be splitted by this and that";
string foo = myString.ToUpper();

string[] byThis = foo.Split(new string[] { "THIS" }, StringSplitOptions.RemoveEmptyEntries);
string[] byThat = foo.Split(new string[] { "THAT" }, StringSplitOptions.RemoveEmptyEntries);

string[] all = foo.Split(new string[] { "THAT", "THIS" }, StringSplitOptions.RemoveEmptyEntries);

Or you can use Regex for that

string[] all = System.Text.RegularExpressions.Regex.Split(myString, "your pattern", System.Text.RegularExpressions.RegexOptions.IgnoreCase);
