示例1: if
string value;
float number;
// Parse a floating-point value with a thousands separator.
value = "1,643.57";
if (Single.TryParse(value, out number))
Console.WriteLine(number);
else
Console.WriteLine("Unable to parse '{0}'.", value);
// Parse a floating-point value with a currency symbol and a
// thousands separator.
value = "$1,643.57";
if (Single.TryParse(value, out number))
Console.WriteLine(number);
else
Console.WriteLine("Unable to parse '{0}'.", value);
// Parse value in exponential notation.
value = "-1.643e6";
if (Single.TryParse(value, out number))
Console.WriteLine(number);
else
Console.WriteLine("Unable to parse '{0}'.", value);
// Parse a negative integer value.
value = "-168934617882109132";
if (Single.TryParse(value, out number))
Console.WriteLine(number);
else
Console.WriteLine("Unable to parse '{0}'.", value);输出：
1643.57 Unable to parse '$1,643.57'. -164300 -1.68934617882109E+17
示例2: if
