Some tips on string conversion

  In the development process, we usually encounter the need to cut strings , You can use some special symbols as separators for strings , such as +、&、| etc. , Then use these symbols to cut the string , Get an array of strings , for example ：

        //string str= "5+30";
public string[] Str2StrArray(string str, char symbol)
    {
        if (string.IsNullOrEmpty(str))
        {
            return new string[0];
        }
        return str.Split(symbol);
    }

  Maybe what you want is Int Array , You can also convert a string to Int, Then get Int Array , for example ：

    //string str= "5+30";
public int[] Str2IntArray(string str, char symbol)
    {
        if (string.IsNullOrEmpty(str))
        {
            return new int[0];
        }

        string[] strArray = str.Split(symbol);
        if (strArray.Length < 1)
        {
            return new int[0];
        }

        int[] value = new int[strArray.Length];
        for (int i = 0; i < strArray.Length; i++)
        {
            value[i] = Convert.ToInt32(strArray[i]);
        }

        return value;
    }

If one-dimensional arrays can not meet your needs , You can add two more split characters , Convert split data to   Crossed array , for example ：

 public int[][] GetIntArray()
    {
        string value = "5+30|10+40|15+45|20+50";
        string[] _strArry = Str2StrArray(value, '|');
        int[][] _temp = new int[_strArry.Length][];
        for (int i = 0; i < _strArry.Length; i++)
        {
            int[] _intArray = Str2IntArray(_strArry[i], '+');
            _temp[i] = _intArray;
        }
        return _temp;
    }
