I've got a bit of a challenge. I have a string which contains of 11 characters, the first 10 denotes an amount, and the last one is a letter or special letter, which represents a value to add.
For example if I got
0000000400A
this means
400 + 2
So the result should be
402
I can't figure out how to do this. Any ideas?

Something like this?
// Setup
var dict = new Dictionary<char, int>();
dict.Add('A', 2);
dict.Add('B', 3);
dict.Add('C', 4);
dict.Add('D', 5);
var str = "0000000400A";
// This is what you need
var result = Convert.ToInt32(str.Substring(0, 10)) + dict[str[10]];
Console.WriteLine(result);

I have the string
"{ "type" : "Stage_FF_Hot_Alerts__c"}"
I want to it be
{ "type" : "Stage_FF_Hot_Alerts__c"}
i.e. I want to remove quotes from start and end. How can I achieve this?

You could use Trim:
var a = "\"{ \"type\" : \"Stage_FF_Hot_Alerts__c\"}\"";
var b = a.Trim('"');
Console.WriteLine(a);
Console.WriteLine(b);
It will remove all leading and trailing quotation marks.
Try it online

You can also use:
var quotedString = "\"hello\"";
var unQuotedString = quotedString.TrimStart('"').TrimEnd('"');

I usually never use char so sorry if it seems a noob question. I'm doing a Crypter, and wanted to do "if there's at least 4 differents char, then crypt, else don't crypt and return error"
Actual Code:
string msg = Console.ReadLine();
char[] msgToChar = msg.ToCharArray();
if(here is the problem)
{
Console.WriteLine("Crypted message: " + Crypt(msg.ToUpper()));
}
else
{
Console.WriteLine("Please enter at least 4 differentes characters.");
}

You could do this to get the distinct count of characters.
msgToChar.Distinct().Count()
So your if would be something like
if (msgToChar.Distinct().Count() >= 4)

This line occur new line in constant error..how can i fix this?
Locations += Environment.NewLine + " map.addOverlay(new GMarker(new GLatLng(" + Latitude + "," + Longitude + ")));";

You can not use "\" string directly in C# code, it produces "new line in constant" error. One of your variables is equal to "\", I can not directly say since the code section you have provided does not include the related initialization code.
instead of using "\", just escape the slash character using "\\".

I want to get the previous chars from a certain char in a string.
For example: myString = "26+", so I want to get 26 without +. How can I do this?

Use Substring and IndexOf.
string str = "26+";
string requiredString = str.Substring(0, str.IndexOf('+'));
strings are immutable in C# and you have to assign the results to string itself or some other string.

The function String.Substring will do what you need.
yourString.Substring(0, keepCharactersBeforeHere);
