文件操作问题--错误：字段初始值无法引用非静态字段。。。

Question

代码是：“StreamWriter sw=new ...    ; sw." 以下即无法继续下去

Answer 1

Hi,

欢迎在MSDN论坛发帖。

你有把这个赋值操作放到一个方法体里面执行吗？

我这边测试，如果把赋值语句放到方法体里面，就没有出现这个问题，如果可以，你可以上传可以重现问题的代码到one drive上面吗？ 这样方便测试， 我下面代码做了字段，属性的测试，你可以查看一下。希望对你有帮助。

 class Program
    {
        public int i = 5;
        public int j = i;  // CS0236  
        public int k;      // initialize in constructor  

        Program()
        {
            k = i;
        }

        public int ty { get; set; } = 4;

        public int te { get; set; } = ty;

      

        void test()
        {
            k = i;
            te = ty;
        }


        static void Main(string[] args)
        {
              int i = 5;
              int j = i; 
    }
    }

Best Regards,

Answer 2

把这一行代码放到方法中，不能直接放在类成员级别。

错误

class A

{

   StreamWriter sw=new ...    ; sw;

}

正确

class A

{

   private void Fun()

{

   StreamWriter sw=new ...    ; sw;

}

}
