一般左值既可以在表达式的左边也可以在右边；
但是右值只能在表达式的右边；
例如：
a = 10; 正确
a=b+10;正确
10 =11； 错误
英文解释如下：
There are two kinds of expressions in C#:
lvalue: An expression that is an lvalue may appear as either the left-hand or right-hand side of an assignment.
rvalue: An expression that is an rvalue may appear on the right- but not left-hand side of an assignment.
但是右值只能在表达式的右边；
例如：
a = 10; 正确
a=b+10;正确
10 =11； 错误
