C# Convert month name to month number

Question

Hi everyone,

i have combobox which i list of all 12 months.

I display there name of each month.

But for the code i must convert it to number.

When i try to convert it i get error "String was not recognized as valid  DateTime".

 

Here is the code:

 

 

//Month name , for example January

string month = comboBox3.Text.Trim();

//Month number according to selected month in combobox3

int month1 = DateTime.ParseExact(month, "MMM",CultureInfo.CreateSpecificCulture("en-GB")).Month;

 

Can you help me?

Thank you.
