问题描述

我班上有这个

私人双fcs_classwork;

i have this in my class

private double fcs_classwork;

public object coresubjectSecond
       {
           get { return fcs_classwork; }
           set { fcs_classwork = value.ToString(); }

请如何解决此问题.

将fcs_classwork声明为double数据类型.因此，您需要将该值转换为double

Here

the fcs_classwork declared as double data type.So you need to convert the value to double

public object coresubjectSecond
       {
           get { return fcs_classwork; }
           set { fcs_classwork = Convert.ToDouble(value);  }
       }

       }

在代码下使用

using under code

public object coresubjectSecond
       {
           get { return fcs_classwork; }
           set { fcs_classwork = Convert.ToDouble(value);  }
       }
