我使用Class创建一个没有主键的SQlite表，如下所示 . 但每次更新时，SQLite都会为每次更新生成记录 . 它应该覆盖它首次创建的相同记录，但不应为每次更新生成记录 .
谢谢 .
Not adding this to the class: [PrimaryKey, AutoIncrement]
class NetworkCredential
{
public string WebServiceName { get; set; }
public string WebServer { get; set; }
public int Port { get; set; }
public string Company { get; set; }
public int DefaultCredential { get; set; }
}
using (var db = new SQLite.SQLiteConnection(DBPath))
{
var User = db.Query("Select * From NetworkCredential").FirstOrDefault();
if (User != null)
{
User.WebServiceName = txtWebServer.Text.Trim();
User.WebServer = txtWebServer.Text.Trim();
User.Port = Convert.ToInt32(txtPort.Text);
int success = db.InsertOrReplace(User);
}
else
{
int success = db.Insert(new NavNetworkCredential()
{
WebServer = txtWebServer.Text.Trim(),
WebServiceName = txtWebServiceName.Text.Trim(),
Port = Convert.ToInt32(txtPort.Text)
});
}
