尝试创建表时,在Xamarin.Android中抛出SQLite.SQLiteException

Question

我正在尝试使用Xamarin.Android创建一个简单的本地SQLite数据库.代码是:

string folder = Environment.GetFolderPath (Environment.SpecialFolder.Personal);
SQLiteConnectiondb = new SQLiteConnection (Path.Combine (folder, "Experimental.db"));
db.CreateTable<Employee>();

我的员工课程是:

[Table("Employees")]
    public class Employee
    {
        [PrimaryKey, AutoIncrement]
        int Id { get; set; }

        string Name { get; set; }

    }

每当代码到达db.CreateTable时,我得到的异常是:

 SQLite.SQLiteException: near ")": syntax error
  at at SQLite.SQLite3.Prepare2 (intptr,string) <IL 0x0002c, 0x00160>
  at at SQLite.SQLiteCommand.Prepare () <IL 0x00011, 0x0008f>
  at at SQLite.SQLiteCommand.ExecuteNonQuery () <IL 0x00013, 0x000b3>
  at at SQLite.SQLiteConnection.Execute (string,object[]) <IL 0x00041, 0x001ab>
  at at SQLite.SQLiteConnection.CreateTable (System.Type,SQLite.CreateFlags) <IL 0x000a4, 0x005cb>
  at at SQLite.SQLiteConnection.CreateTable<Core.Employee> (SQLite.CreateFlags) <0x00063>

对于我没有经验的人来说,这看起来像是一个与SQLite本身相关的问题.有没有其他人面对这个,如果是这样 - 你的工作是什么？

使Employee类的属性公开,以便SQLite在为表创建列时可以看到它们:

[Table("Employees")]
public class Employee
{
    [PrimaryKey, AutoIncrement]
    public int Id { get; set; }

    public string Name { get; set; }

}
