How can I check if a string contains a character in C#?
(8 answers)
Closed 5 years ago.
How I can check if my string has the value ".all" in. Example:
string myString = "Hello.all";
I need to check if myString has .all in order to call other method for this string, any ideas how I can do it?
you could use myString.Contains(".all")
More info here
Use IndexOf()
var s = "Hello.all";
var a = s.IndexOf(".all", StringComparison.OrdinalIgnoreCase);
If a = -1 then no occurrences found
If a = some number other than -1 you get the index (place in the string where it starts).
So a = 5 in this case
Simply call .Contains(".all") on the string object:
if (myString.Contains(".all")
{
// your code to call the other method goes here
}
There is no need for regex to do that.
Optionally, as mentioned by #ZarX in comments, you can check if the string ends with your keyword with .EndsWith(".all"), which will return true if the string ends with your keyword.

I have a string variable called price which contains a range of price pattern as you can see in code. I want to filter it by its first part only.
string price = "9.99 - 12.99";
i already tried like bellow but this gives me wrong output something like ".99" however this is not my target output i am looking for.
string result = price.Substring(1, price.IndexOf("-") - 1);
The output i want like this- "9.99". Now can i filter this part from that string? Thanks in advance
Strings in C# are zero-based, so when you set the starting character as 1, you're in fact starting from the second character. Just use 0 and you should be OK:
string result = price.Substring(0, price.IndexOf("-") - 1);
Note, by the way, that you could use the full " - " delimiter instead of playing around with index arithmetic:
string result = price.Substring(0, price.IndexOf(" - "));
You're close but note that strings are 0 indexed:
string result = price.Substring(0, price.IndexOf("-") - 1);

How can I check if a string exists in another string
(10 answers)
Closed 5 years ago.
I'm working on a Existing Class file(.cs) which fetches a string with some data in it.
I need to check if the string contains a word. String has no blank spaces in it.
The string-
"<t>StartTxn</t><l>0</l><s>0</s><u>1</u><r>0</r><g>1</g><t>ReleaseUserAuthPending</t>"
I need to check if the string contains 'ReleaseUserAuthPending' in it.
You can try this:
var strValue = "<t>StartTxn</t><l>0</l><s>0</s><u>1</u><r>0</r><g>1</g><t>ReleaseUserAuthPending</t>";
if (strValue.Contains("ReleaseUserAuthPending"))
{
//Do stuff
}
Refer About String - Contains function
For your information: Contains function is case-sensitive. If you want to make this Contains function as case-insensitive. Do the following step from this link.
bool containsString = mystring.Contains("ReleaseUserAuthPending");
Try
String yourString = "<t>StartTxn</t><l>0</l><s>0</s><u>1</u><r>0</r><g>1</g><t>ReleaseUserAuthPending</t>";
if(yourString.Contains("ReleaseUserAuthPending")){
//contains ReleaseUserAuthPending
}else{
//does not contain ReleaseUserAuthPending
}

Make first letter of a string upper case (with maximum performance)
(42 answers)
Closed 7 years ago.
I have already taken a look at such posts like:
Format to first letter uppercase
How to capitalise the first letter of every word in a string
But none of these seem to actually work. I would have thought to start with that there would just be a:
.Capitalize();
Like there is:
.Lower(); & .Upper();
Are there any documentation or references regarding converting to a string like the following?
string before = "INVOICE";
To then becoming:
string after = "Invoice";
I receive no errors using the way the posts solutions I read give me, however, the before still remains capitalized.
What about using ToUpper on the first char and ToLower on the remaining string?
string after = char.ToUpper(before.First()) + before.Substring(1).ToLower();
You can create a method that does something like this:
string UppercaseFirst(string str)
{
if (string.IsNullOrEmpty(str))
return string.Empty;
return char.ToUpper(str[0]) + str.Substring(1).ToLower();
}
And use it like this:
string str = "thISstringLOokSHorribLE";
string upstr = UppercaseFirst(str);
to get this:

How to remove a string from a string
(4 answers)
Closed 8 years ago.
I've this kind of string.
FullName:ae876ggfg777878848adgf877
And I want to remove "FullName:", so the output as follows:
ae876ggfg777878848adgf877
How can I do that?
I tried this:
var index = myText.IndexOf(":");
var result = myText.Remove(index);
But the output is like this:
FullName
Which I do not expect.
IndexOf returns the index of whatever string/character you give it, so in your case, the index of :.
Remove, according to the documentation:
Returns a new string in which all the characters in the current instance, beginning at a specified position and continuing through the last position, have been deleted.
So what's happening here is you're removing everything after and including the :
You should be using String.Replace:
string removed = myText.Replace("FullName:", "");
Use String.Substring() and get the start index by using String.IndexOf('character') + 1.
string s = "FullName:ae876ggfg777878848adgf877";
Console.WriteLine(s.Substring(s.IndexOf(':')+1));

How to get the last five characters of a string using Substring() in C#?
(12 answers)
Closed 9 years ago.
I have a string that could look like this: smithj_Website1 or it could look like this rodgersk_Website5 etc, etc. I want to be able to store in a string what is after the "_". So IE (Website1, Website5,..)
Thanks
Should be a simple as using substring
string mystr = "test_Website1"
string theend = mystr.SubString(mystr.IndexOf("_") + 1)
// theend = "Website1"
mystr.IndexOf("_") will get the position of the _ and adding one to it will get the index of the first character after it. Then don't pass in a second parameter and it will automatically take the substring starting at the character after the _ and stopping and the end of the string.
int startingIndex = inputstring.IndexOf("_") + 1;
string webSite = inputstring.Substring(startingIndex);
or, in one line:
string webSite = inputstring.Substring(inputstring.IndexOf("_") + 1);
