读取堆栈跟踪时:
[FormatException: Input string was not in a correct format.]
System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal) +2755599
System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info) +112
System.Convert.ToInt32(String value) +68
+68,+ 112等数字是什么意思.我猜他们已经抵消了什么.如果是这样,什么？
