一、C++的int转string #方法一: 使用itoa函数: char * itoa ( int value, char * str, int base ); 说明:Convert integer to string (non-standard function) 参数: ·value : Value to be converted to a string.·str : Array in memory where to store the resulting null-terminated string.·base...
// The String value '1601.9' is not in a recognizable format. // Converted the String value '2147483647' to the Int32 value 2147483647. 備註 ToInt32(String)使用方法相當於傳遞value至Int32.Parse(String) 方法。 value 會使用目前文化特性的格式化慣例來解譯。 如果您不想在轉換失敗時處理例外狀況,您...
