C# 分部类读取学生信息

本文主要介绍如何使用分部类，存储学生信息，并读取到控件中。

知识点

在类中定义字段时，将字段的数据类型修改为object

csharp 复制代码

        partial class CommInfo
        {
            /// <summary>
            /// 编号
            /// </summary>
            public object ID;
            /// <summary>
            /// 姓名
            /// </summary>
            public object Name;
            /// <summary>
            /// 性别
            /// </summary>
            object sex;
            public object Sex
            {
                get
                {
                    if ((bool)sex == true)
                        sex = "男";
                    else
                        sex = "女";
                    return sex;
                }
                set { sex = value; }
            }
            /// <summary>
            /// 年龄
            /// </summary>
            public object Age;
            /// <summary>
            /// 出生年月
            /// </summary>
            public object Birthday;
        }
