Question

我已经在我的C＃程序中将数据库表读入DataTable，但是我有一些问题将包含位值的列分配给布尔值。

到目前为止，这是我的代码：

            // Load and Sort Users DataTable
        DataTable datatableUsers = UserMethods.GetUsers().Tables["Users"];
        datatableUsers.DefaultView.Sort = "Name";

        // Filter Based on Search Box
        datatableUsers.DefaultView.RowFilter = "Name LIKE '%" + user + "%' OR Username LIKE '%" + user + "%'"; ;  
        DataView dataviewUsers = datatableUsers.DefaultView;

        // Loop Through Rows and Add UsersGrid to FlowLayoutPael
        foreach (DataRowView datarowviewUsers in dataviewUsers)
        {
            var UsersGrid = new UsersGrid
            {
                ID = (int)datarowviewUsers["ID"],
                Username = datarowviewUsers["Username"].ToString(),
                User = datarowviewUsers["Name"].ToString(),
                Admin = datarowviewUsers["Administrator"].ToString(),
            };
            flowlayoutpanelUsers.Controls.Add(UsersGrid);
            UsersGrid.WasClicked += UsersGrid_WasClicked;
        }

目前我正在转换Admin ToString并匹配“True”，但这样做非常混乱，我宁愿将Admin设置为输入Boolean。我需要做什么？

Answer 1

您可以使用内联if运算符。例如：

Admin = datarowviewUsers["Administrator"].ToString() == "True" ? true : false

Answer 2

根据deepee1的回答，我认为它会返回一点价值。

Admin = datarowviewUsers["Administrator"].ToString() == "1" ? true : false;
