当iam使用

convert.ToDouble由于输入字符串的格式不正确，我引发了期望.

convert.ToDouble it is throwing expection as input string was not in correct format how can i validate

my number display should be like that only as above

推荐答案

{8888)
删除逗号并尝试进行转换.ToDouble

Hi,

{8888)
Remove comma and try on that convert.ToDouble

改为使用Parse:

Use Parse instead:

string data = "8,000";
double d = double.Parse(data, NumberStyles.AllowThousands);

可以尝试一下，

Can Try this,

string s = "123,456.78";
        double value;
        bool flag = double.TryParse(s, NumberStyles.Currency, CultureInfo.CurrentCulture.NumberFormat, out value);
        if (flag)
        {
            Console.WriteLine("Entered Amount is :" + value);
        }
