如果解析失败,Int32.Parse(source)总会抛出异常;Convert.ToInt32(source)在source为null的情况下不会抛出异常而是简单的返回0给调用方;而Int32.TryParse(source, result)则无论如何都不抛出异常,只会返回true或false来说明解析是否成功,如果解析失败,调用方将会得到0值。 Q:如果我要解析的字符串的字面数值不是十...
int numVal = Convert.ToInt32("29"); numVal++; Console.WriteLine(numVal); // Output: 30 將string 轉換為 int 的另一個方法是透過 System.Int32 結構(Struct) 的 Parse 或TryParse 方法。ToUInt32 方法會在內部使用 Parse。如果字串的格式無效,Parse 會擲回例外狀況,而 TryParse 不會擲回例...

Converting string to int type value can be done through the following methods.static int parseInt(String s) parses the string argument as a signed decimal integer. static int parseInt(String s, int radix) parses the string argument in the radix specified by the second argument. static Integer...
long int strtol (const char* str, char** endptr, int base); that parses the C-string str interpreting its content as an integral number of the specified base. strtol skips white spaces, interprets integer and set pointer *endptr to the first character following the integer. Since author...
