Textarea problem ... please help

i created an textarea using

Code (CSharp):

1. stringToedit= GUI.TextArea (new Rect (5, 5, 350, 200), stringToedit);

but when i want to change for example stringToedit[2] ="a";

i get this error:
Property or indexer string.this[int] cannot be assigned to (it is read-only)

i also tried the declaration with get and set but didn't work :/

so i wanna first show an TextArea and then i wanna get this string to edit it
for exampe :

Code (CSharp):

1. myString= GUI.TextArea (new Rect (5, 5, 350, 200), myString);
2. for(int i=0 ; i < myString.Length ; i++ ) {
3. if ( myString[i] ==" "){
4. myString[i] = "a";
5. }
6. }
7.  

so i get the string then i'll test if there an blank space to replace it with "a"

i also tried the string methods but not working :/


ho to do that please

 

This is not a limitation of the textarea or anything, it is not allowed to set string values through the char array like that. What I recommend doing is this:

Code (CSharp):

1. myString = myString.Replace(' ', 'a');

This replaces all space chracters with an a character. btw ' is for characters, " is for strings.
