我是这个字符串:
@Transactional
public Company updateCompany(Company company, final CompanyDto form) {
company.getCompanyObjects().clear();
company.getCompanyObjects().addAll(form.getCompanyObjects());
for(CompanyObject obj : company.getCompanyObjects()){
obj.setCompany(company);
}
return companyRepository.save(company);
}
此字符串最初采用以下格式:
QueryBuilder<Account, String> qb = accountDao.queryBuilder();
Where where = qb.where();
// the name field must be equal to "foo"
where.eq(Account.NAME_FIELD_NAME, "foo");
// and
where.and();
// the password field must be equal to "_secret"
where.eq(Account.PASSWORD_FIELD_NAME, "_secret");
PreparedQuery<Account, String> preparedQuery = qb.prepareQuery();
所以我使用Regex表达式删除了Corso Vittorio Emanuele II 9 20122 Milano
:
Corso Vittorio Emanuele II 9
20122
Milano
现在我试图以这种方式删除空格:
NewLine
但它没有按预期工作,&#39;因为我得到了这个结果:
var stringWithoutNewLine = Regex.Replace(text, "\t|\n|\r", string.Empty).Trim();
什么时候应该:
return Regex.Replace(stringWithoutNewLine, @"\s+", string.Empty);
答案 0 :(得分:2)
将正则表达式从@"\s+"
更改为@"\s{2,}"
。它将删除从2到(种类)无限数重复的空格。然后,正如Juharr所说,用空格替换:
Regex.Replace(yourString, @"\s{2,}", " ");

你真的需要使用正则表达式吗?为什么不这样呢?
var splitString = text.Split(new char[0],StringSplitOptions.RemoveEmptyEntries);
var stringWithoutExtraSpaces = string.Join(" ",splitString);
