推荐答案

异常是正确的.如何解决此问题?将"sidd"之类的字符串转换为双精度.
尝试将"10"转换为双精度，它将起作用.

Exception is correct. How can you convert a string like "sidd" to a double.
Try converting "10" to double, it will work.

如果您要将字符串转换为数字，则字符串的值必须为number.

例如:string str ="445"; //可能
字符串str ="abcd"; //不可能

If u want to convert a string to a number , the values of the string must be number.

Eg : string str = "445"; // Possible
string str = "abcd"; // Not Possible

您好，Siddharth，
尝试了解.您不能将这种类型的字符串值更改为double.因为这是真实的字符串.您如何将自己的名字改成两倍.这可能吗.你可以做到的...

Hi Siddharth,
try to understand. you can not change this type of string value into double. beacuse this is real string. How can you change your name into double. is this possible. You can do this...

String str="50";
double doubleValue=Convert.ToDouble(str);

现在它将使您返回双值....
