Question

我有String之类的地址"abc 201 lmn road pqr near xyz building state maharashtra navi mumbai, 4212001 .... "

我想将此字符串拆分为

List<string> addrList = new List<string>();
addrList.add("abc 201 lmn road pqr near");
addrList.add("xyz building state maharashtra ");
addrList.add("navi mumbai, 4212001");

我尝试了以下功能

private string[] splitToNChar(string inputString, int chunkSize)
    {

        List<string> myList = new List<string>();
        for (int i = 0; i < inputString.Length; i += chunkSize)
        {
            myList.Add(inputString.Substring(i, chunkSize));
        }
        return myList.ToArray(); 
    }

，但是当我以40个字符的形式传递块大小时，它具有例外，例如

抛出异常：mscorlib.dll中的'System.ArgumentOutOfRangeException' eee例外：索引和长度必须指代字符串。

如果inputString是"abc 201 lmn road pqr near xyz building state maharashtra navi mumbai, 4212001 .... "

扩展功能的结果是：

private string[] splitToNChar(string inputString, int chunkSize)
{
    if (chunkSize > inputString.Length)
        throw new Exception("input string (" + inputString.Length + ") is smaller than chunksize (" + chunkSize + ")");

    List<string> myList = new List<string>();
    for (int i = 0; i < inputString.Length; i += chunkSize)
    {
        if (i + chunkSize < inputString.Length)
            myList.Add(inputString.Substring(i, chunkSize));
        else
            myList.Add(inputString.Substring(i)); //ADD REST OF STRING
    }
    return myList.ToArray();
}

输出：

[0]  abc 201 lmn road pqr near
[1]   xyz building state mahar
[2]  ashtra navi mumbai, 42120
[3]  01 ....

希望我能正确理解您的问题。
