将字符串转换为特定的int

string value = "123";
try
{
    int number = int.Parse(value);
    Console.WriteLine(number);
}
catch (FormatException)
{
    Console.WriteLine("字符串格式不正确");
}
catch (OverflowException)
{
    Console.WriteLine("数值超出了 int 的范围");
}

string value = "123";
if (int.TryParse(value, out int number))
{
    Console.WriteLine(number);
}
else
{
    Console.WriteLine("转换失败");
}

string hexValue = "1A3F";
int number = int.Parse(hexValue, System.Globalization.NumberStyles.HexNumber);
Console.WriteLine(number);  // 输出：6719

string currencyValue = "$1,234";
int number = int.Parse(currencyValue, System.Globalization.NumberStyles.Currency);
Console.WriteLine(number);  // 输出：1234
