如何修剪字符串并将其转换为整数？

Question

我如何修剪和转换字符串如下:

string abc = "15k34"
int x = first two characters of abc // should be 15
but if abc begins with "0"
for example - string abc = "05k34"
int x = first two characters of abc // should be 5

尝试使用以下代码:

            string str = "15k34";
            int val;
            if (str.Length>1)
            {
                if (int.TryParse(str.Substring(0, 2), out val))
                {
                    //val contains the integer value
                }

            }
