manipulating a string

22y3.7kVisual Basic .NET

Hi, I was wondering if anyone knows how I could change a few things in a string. Say something returns a string like "a table" or "a chair". How can I remove the a and capatalize the t or c so it comes out like this: "Table" or "Chair". I've tried to remove the first to bits of the string by doing str.Remove(0, 2). After that, i've tried using ToCharArray() and doing this: char[] stra = str.ToCharArray(); then stra[0].ToUpper(); Although this doesn't work. After i've made it look like Table or Chair I need to return a string not char[] or char. I'm am very new to C# and this is my first bit of string manipulation, sorry if i've gone way off the track here. Thanks for any help. gordy

One more way to do it: string tmp = "test"; tmp = tmp.Substring(0,1).ToUpper() + tmp.Remove(0,1);

Try this: using System; namespace ConsoleTesting { class UpperCase { static void Main(string[] args) { string test = "testing..."; char[] chars = test.ToCharArray(); string Upper = chars[0].ToString().ToUpper(); chars[0] = Upper[0]; string result = string.Empty; for(int i = 0; i < chars.Length; i++) { result += chars[i]; } Console.WriteLine(result); Console.Read(); } } }

Thats what I have tried in my first post. Although i'm not to sure how to convert the whole thing back to a new string. If anyone could help me, that would be great. Thanks

Strings are immutable classes, so you can't "change" a character in them. If you need to perform manipulations at that level, it will be more efficient to convert the string to a char array, capitalize the first t in test, then convert back to a string.

Thanks for the reply although I want to only capatalize one letter within the string. This is where my problem is I think. So capatalize the first t in test.

Hi The modified string will be returned. This is a copy of the original string, but modified. string str1 = "Test"; string str2 = str1.ToUpper(); // str2 == "TEST" ... or string str1 = "Test"; string str2 = str1.Remove(0,1); // str2 == "est" If you wannt you can use the same string: string str1 = "Test"; str1 = str1.ToUpper(); // str1 == "TEST" Cheers Simon
