char to string fails

[dave]

char[] ch = new char[1];

ch[0]="-";

FileStream fp=new FileStream("z:\ \" + "math" + ch[0].ToString() +
"optpivot",File Mode.Open,FileA ccess.Read);



Why does this fail with Cannot implicitly convert type 'string' to 'char'
(CS0029) ?

Re: char to string fails

double quotes indicate string type, single quotes indicate char type
so try:

ch[0] = '-';

Re: char to string fails

David,

It's this line:

ch[0]="-";

It should be:

ch[0]='-';

Note the single quotes which are used to indicate a character literal.

RE: char to string fails

As the exception message indicates, there is no implicit cast from string to
char.
Use this instead (with single quote marks):
ch[0]='-';
