sprintf() equivalent in C#

Question

C++:

sprintf(formattedDate, "%02d/%02d/%02d", Month, Day, Year);

C#:

public char[] formattedDate = new char[255];
public int Month;
public int Day;
public int Year;

string.Format(formattedDate, "%02d/%02d/%02d", Month, Day, Year);

I tried the above C# code but it throws error. Need a fix.

Answer 1

Perhaps you should explain what you're trying to do.

For those of us who don't know c++ well enough to guess.

Oh.

And you posted to the wpf forum.

There's a c# forum which would have been more appropriate.

Read the docs; https://msdn.microsoft.com/en-us/library/system.string.format%28v=vs.110%29.aspx?f=255&MSPPError=-2147217396

Answer 3

The string.Format method in C# returs a string that can store directly in a string variable:

string strFormattedDate  = string.Format("{0}{1}{2}", Month, Day, Year);

Each format item to be replace by the argument(s) is specified using the {x} syntax where x is the index of the parameter to be inserted: https://msdn.microsoft.com/en-us/library/system.string.format(v=vs.110).aspx

Answer 4

That's "ok" but you may want the data to be formatted as a specific number type, in which case you need the addition syntax, similar to printf.
