不包含适合于入口点的静态“Main”方法/does not contain a static 'Main' method suitable for an entry point
error:as subject
solution:
1. Must be declared as static
2. Main, is defined with the wrong case, such as lower-case main.
3. must return void or int
4. it must have either no parameters or else one parameter of type string[]
static void Main()
{
// Create objects by using the new operator:
...
// Create an object using the default constructor:
...
// Display results:
...
}
}
