如何在C＃中将指数字符串转换为普通字符串

Question

I am reading a column number from csv where the number is 123456791234567 however due to format it gets converted to number="1.23457E+14" in the csv file.

is there any way where we can change it to original string using c# ? I am trying with below code :

decimal number = Decimal.Parse(number,System.Globalization.NumberStyles.Any);

but the number i am getting is 123457000000000M and the actual number is 123456791234567

any idea on this?

If I understand correctly, excel is converting 123456791234567 to 1.23457E+14 . In that case, you just need to format the excel cell (or potentially the column) containing the value to string, before you set the value.

If the C# program opens the csv to find the value to be 1.23457E+14 , then there is no way for you to convert it back to 123456791234567 , since the precision is already lost - unless of course the same value exists (or can be recreated) in other cells (columns)
