Mystring[0] should be enough
The difference between MyString[0] and MyString.ToCharArray()[0] is that the former treats the string as a read-only array, while ToCharArray() creates a new array. The former will be quicker (along with easier) for almost anything where it will work, but ToCharArray can be necessary if you have a method that needs to accept an array, or if you want to change the array.
If the string isn't known to be non-null and non-empty you could do:
string.IsNullOrEmpty(MyString) ? (char?)null : MyString[0]
which returns a char? of either null or the first character in the string, as appropriate.
Try this,
string s1="good";
string s=s1.Substring(0,1);
In C# 8 you can use ranges.
myString[0..Math.Min(myString.Length, 1)]
Add a ? after myString to handle null strings.
You can use LINQ
char c = mystring.FirstOrDefault()
It will be equal to '\0' if the string is empty.
I think you are looking for this MyString.ToCharArray()[0]
:)
But you can use MyString[0] too.
Just another approach:
string mystr = "hello";
MessageBox.show(mystr.Substring(0, 1));
Following example for getting first character from a string might help someone
string anyNameForString = "" + stringVariableName[0];
MyString.Remove(1, 2); also works
getting a char from a string may depend on the enconding (string default is UTF-16)

string str = new String(new char[] { '\uD800', '\uDC00', 'z' });
string first = str.Substring(0, char.IsHighSurrogate(str[0]) ? 2 : 1);
Answer to your question is NO.
Correct is MyString[position of character]. For your case MyString[0], 0 is the FIRST character of any string.
A character value is designated with ' (single quote), like this x character value is written as 'x'.
A string value is designated with " ( double quote), like this x string value is written as "x".
So Substring() method is also does not return a character, Substring() method returns a string!!!
A string is an array of characters, and last character must be '\0' (null) character. Thats the difference between character array and string ( which is an array of characters with last character as "end of string marker" '\0' null.
And also notice that 'x' IS NOT EQUAL to "x". Because "x" is actually 'x'+'\0'.
Or you can do this:
MyString[0];
