String split by length

Use String.SubString.

var bar = foo.Substring(0, 25);

bar will contain the first 25 characters of foo.

var bar = foo.Substring(index, length);

bar will contain length characters from foo, starting from index.

If you want to create a function that chops a string by length and return an array of those strings, here's one in C#:

public static string[] Chop(string value, int length)
{
    int strLength = value.Length;
    int strCount = (strLength + length - 1) / length;
    string[] result = new string[strCount];
    for (int i = 0; i < strCount; ++i)
    {
        result[i] = value.Substring(i * length, Mathf.Min(length, strLength));
        strLength -= length;
    }
    return result;
}

Example usage:

string bar = "t$$anonymous$$s is an incredible long string that will be chopped down"; string[] foo = Chop(bar, 10);

If you want you can make it an extension to string.

public static class StringChop
{
    public static string[] Chop(t$$anonymous$$s string value, int length)
    {
        int strLength = value.Length;
        int strCount = (strLength + length - 1) / length;
        string[] result = new string[strCount];
        for (int i = 0; i < strCount; ++i)
        {
            result[i] = value.Substring(i * length, Mathf.Min(length, strLength));
            strLength -= length;
        }
        return result;
    }
}

Then you can use it like t$$anonymous$$s:

string bar = "t$$anonymous$$s is an incredible long string that will be chopped down"; string[] foo = bar.Chop(10);
