Is it possible to `continue` a foreach loop while in a for loop?

Question

Okay, so what I want to do should sound pretty simple. I have a method that checks every character in a string if it's a letter from a to m. I now have to continue a foreach loop, while in a for loop. Is there a possible way to do what I want to do?

public static string Function(String s)
{
    int error = 0;
    foreach (char c in s)
    {
        for (int i = 97; i <= 109; i++)
        {
            if (c == (char)i)
            {
                // Here immediately continue the upper foreach loop, not the for loop
                continue;
            }
        }
        error++;
    }

    int length = s.Length;
    return error + "/" + length;
}

If there's a character that's not in the range of a to m, there should be 1 added to error. In the end, the function should return the number of errors and the number of total characters in the string, f.E: "3/17".

Edit

What I wanted to achieve is not possible. There are workarounds, demonstrated in BsdDaemon's answer, by using a temporary variable.

The other answers fix my issue directly, by simply improving my code.

You can do this by breaking the internal loop, this means the internal loop will be escaped as if the iterations ended. After this, you can use a boolean to control with continue if the rest of the underlying logic processes:

    public static string Function(String s)
    {
        int error = 0;
        foreach (char c in s)
        {
            bool skip = false; 

            for (int i = 97; i <= 109; i++)
            {
                if ('a' == (char)i)
                {
                    skip = true;
                    break;
                }
            }

            if (skip) continue;
            error++;
        }
        string length = Convert.ToString(s.Length);
        return error + "/" + length;
    }
