Question

在此行向数据库添加数据（在Windows手机应用程序上）时出现此错误：

if (concac.DatabaseExists())
{
   concac.Cacs.InsertOnSubmit(fullname);
   concac.SubmitChanges();
}

这就是错误：

   at System.Data.SqlServerCe.SqlCeResultSet.InternalInsert(Boolean fMoveTo, Object sender, SqlCeUpdatableRecord record)

听起来我需要检查数据库的权限。例如，在MSSQL中，您必须在使用SELECT或UPDATE语句时授予权限（每个用户）。

Windows手机上的权限被拒绝数据库
