You can use the Substring method to get any number of characters from a string at any given location. However, if you only want a single character, you can use the string indexer to get a single character at any given index like you do with an array:
string s = "hello";
char c = s[1]; //...

You can create a new branch and switch to it using
git checkout -b AP-57
After you use git checkout to create a new branch, you will need to set that upstream origin to push to using
git push --set-upstream origin AP-57
After that, you can use git push while you are on that branch.
By default a property is a primary key if a property on a class is named “ID” (not case sensitive), or the class name followed by "ID". If the type of the primary key property is numeric or GUID it will be configured as an identity column. Simple Example:
public class Room

To get template item by template Id.
TemplateItem templateItem = Sitecore.Context.Database.GetTemplate(new ID("{11111111-1111-1111-1111-111111111111}"));
Input the name of the template to get the template by using GetTemplate Method.
TemplateItem templateItem = Sitecore.Context.Database.GetTemplate("NameOfTheTemplate");
When you have an input with well defined boundaries and are expecting more than one match in your string, you have two options:
Using lazy quantifiers;
Using a negated character class.
Consider the following:
You have a simple templating engine, you want to replace substrings like $[foo] whe...
[^0-9a-zA-Z]
This will match all characters that are neither numbers nor letters (alphanumerical characters). If the underscore character _ is also to be negated, the expression can be shortened to:
[^\w]
Or:
\W

Dynamic scoping means that variable lookups occur in the scope where a function is called, not where it is defined.
$ x=3
$ func1 () { echo "in func1: $x"; }
$ func2 () { local x=9; func1; }
$ func2
in func1: 9
$ func1
in func1: 3
In a lexically scoped language, func1 would alway...
If you have an instance of a generic type but for some reason don't know the specific type, you might want to determine the generic arguments that were used to create this instance.
Let's say someone created an instance of List<T> like that and passes it to a method:
