Question

我有个人身份证和行业ID，我想彼此比较，但行业编号前面有零和字母字符。有些数字比其他数字更长。

离。

Personal Number | Industry Number
123             | J000123              
1234            | L001234
12345           | M012345

如果它只是零，我知道如何解决问题。性格引发了我，我将如何实现这一目标？

Answer 1

我假设PersonalNumber是Int，而IndustryNumber的类型为String

bool Result = int.Parse(string.Concat(PersonalNumber.Skip(1))) == IndustryNumber;

Answer 2

对于更新的问题（即行业编号以任意字母开头，后跟由零填充的数字），可能是

// Remove 1st letter, than remove zeros
String number = IndustryNumber.Substring(1).TrimStart('0');

if (number.Equals(personalNumber)) {
  ...
}

Answer 3

使用RegEx：

var numb = int.Parse(RegEx.Match(industryNumber, @"\d+^").Value);
//Then compare the two ints

Answer 4

为下面的给定代码创建一个函数

  string a = "str123";
    string b = string.Empty;
    int val;

    for (int i=0; i< a.Length; i++)
    {
        if (Char.IsDigit(a[i]))
            b += a[i];
    }

    if (b.Length>0)
        val = int.Parse(b);

然后调用getInt（mystring）== int

    Regex.Replace("J0123", "([A-z]*)", "");

Answer 5

您可以使用正则表达式删除行业编号的第一部分：

Regex.Replace("J0123", "J0*", "");

结果为＆＃34; 123＆＃34;

更新，考虑所有使用此正则表达式的字母：

Regex.Replace("J0123", "[A-Z]0*", "");

Answer 6

您需要在行业编号和转换后使用substring（）：我假设你使用一个2维的字符串数组。 string [，] myarray。

<access origin="*" />

Answer 7

假设您有两个用于PersonalId和IndustryID.Result的数组是另一个将保存结果的数组。

for(int i=0; i< PersonalID.Count i++)
{
if(IndustryID[i].Contains(PersonalID[i]))
{
Result[i]=true;
}
else
Result[i]=False;
}

从字符串中提取整数
