问题 I'm trying to figure out if there is a good way to manage units in my pandas data.

问题 How to set/enforce common format for entire application? For grids and controls like dateTimePicker just to not worry about it while developing? I tried to set in my own wrapper on controls but every time I run the designer this value is overwritten. I'm afraid that when I want to change it I'd have to change it everywhere! that's creepy ;) Another thought was to set it in .cs file in SetInitValues( customformat = Format+From_Config_file_or_settings;) or something..?

How would I separate thousands with space in C#

阅读更多关于 How would I separate thousands with space in C#

问题 Assume I have the following decimal number that I have to format so that every thousand should be separated with a space: 897.11 to 897.11 1897.11 to 1 897.11 12897.11 to 12 897.11 123897.11 to 123 897.11 I have tried Decimal.ToString("0 000.00").

问题 I'm trying to set a number format (South African Rand currency, no decimals) to a range like so: range.NumberFormat = "_ R * # ##0_;"; where range is of type Microsoft.Office.Interop.Excel.Range however when I open the spreadsheet and check the formatting string by choosing custom format the string now looks like this: _ \R * #\ ##0_; and these added slashes means that only the first thousand separator (a space) is present and the rest are left off. I've also tried this: range.NumberFormat =

C# - String formatting: double fixed width

阅读更多关于 C# - String formatting: double fixed width

问题 How can I use String.Format in C# so doubles are displayed like this: Values: -1.0 1.011 100.155 1000.25 11000.52221 displayed string: -1.00 1.011 100.2 1000 11001 The main point is my width is fixed to 5 characters no matter what.
