minimize length of string in C#

Question

I want to reduce the length of a string. Like...

This string...

string foo ="Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aenean in vehicula nulla. Phasellus libero dui, luctus quis bibendum sit amet";

Becomes this string...

Lorem ipsum dolor sit amet, consectetur adipiscing...

How do I do this? Thanks!

Answer 1

string foo ="Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aenean in vehicula nulla. Phasellus libero dui, luctus quis bibendum sit amet";

string small_foo = foo.SubString(0, 50);

Using Substring to get the first 50 characters of the string. http://msdn.microsoft.com/en-us/library/aka44szs.aspx

Answer 2

Code

public string Truncate(string input, int length)
{
    if (input.Length < length) return input;
    int index = input.IndexOf(' ', length);
    return input.Substring(0, index) + "...";
}

...

string foo ="Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aenean in vehicula nulla. Phasellus libero dui, luctus quis bibendum sit amet";

string bar = Truncate(foo, 50);
Console.WriteLine(bar);

Output

Lorem ipsum dolor sit amet, consectetur adipiscing...

Instead of

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aenean in vehicula nulla. Phasellus libero dui, luctus quis bibendum sit amet
