// The String value '1601.9' is not in a recognizable format. // Converted the String value '2147483647' to the UInt32 value 2147483647. 注解 ToUInt32(String)使用 方法等效于将 UInt32.Parse(String) 传递给 value 方法。 value 通过使用当前区域性的格式设置约定进行解释。 如果不想在转换失败时处...
The Convert Number to String method converts a number to a string. It returns a string representation of this number. It uses the following precision in the returned string: Single-precision for an integer or for a single-precision numeric expression. Double-precision for a long number or for...
You convert a string to a number by calling the Parse or TryParse method found on numeric types (int, long, double, and so on), or by using methods in the System.Convert class.It's slightly more efficient and straightforward to call a TryParse method (for example, int.TryParse("...
