Errors with Methods and Classes ( Threading )
May 4 2011 12:35 PM
C# 4.0 using SharpDevelop
These are the errors I get with the following program
.
in
Program
.
cs Line
21
Error = Argument1:cannot convert
from
'void'
to
'System.Action'
(
CS1503
)
in
Program
.
cs Line
21
Error = The best overloaded method match
for
'voidoverrideproblem.ThreadClass1.SeparateThread(System.Action)'
has some invalid
arguments
(
CS1502
)
Its three files
.
Each one is named with the source code to it
.
Uncomment ( // ) one of the two choices in the Program.cs file to see the problem. One works, the other does not. The one that does not work is the one I need to solve the answer too.
I just cannot seem to figure out how to solve this so that it works
.
Anyone have any ideas on this
?
// Program.cs
using
System

namespace
voidoverrideproblem
{
class

args

{

thenumber =
"25565"
;
DisplayTheNumber runnumber =
new
DisplayTheNumber
();
ThreadClass1 startthread =
new
ThreadClass1
();
// Choice 1 here works.
// runnumber.DisplayNumber(thenumber);
// Choice 2 does not.
