DuplicateKeyException in LINQ, but I've set auto increment and auto sync
- by Fritos
I'm getting a DuplicateKeyException error in my C# code.
I've set Auto Generated = true, and Auto-Sync = OnInsert in my dbml. I'm not even touching the PK field in any manually written code (as seen below [My primary key field is actually called PK]).
using (DeviceExerciseDataDataContext context = new DeviceExerciseDataDataContext())
{
foreach(Data tgudData in data.Data)
{
tgd = new tableData();
tgd.FK = key;
tgd.Time = tgudData.TimeStamp;
tgd.Calories = Convert.ToInt32(tgudData.Calories);
tgd.HeartRate = tgudData.AvgHr;
tgd.BenchAngle = tgudData.Angle;
tgd.WorkoutTarget = 0;
tgd.Reps = tgudData.Reps;
context.tableDatas.InsertOnSubmit(tgd);
}
context.SubmitChanges();
}
This is the code for the column in the designer (columns are named PK and FK)
[global::System.Data.Linq.Mapping.ColumnAttribute(Storage="_PK", AutoSync=AutoSync.OnInsert, DbType="Int NOT NULL", IsPrimaryKey=true, IsDbGenerated=true)]
public int PK
{
get
{
return this._PK;
}
set
{
if ((this._PK != value))
{
this.OnPKChanging(value);
this.SendPropertyChanging();
this._PK = value;
this.SendPropertyChanged("PK");
this.OnPKChanged();
}
}
}
[global::System.Data.Linq.Mapping.ColumnAttribute(Storage="_FK", DbType="Int")]
public System.Nullable<int> FK
{
get
{
return this._FK;
}
set
{
if ((this._FK != value))
{
this.OnFKChanging(value);
this.SendPropertyChanging();
this._FK = value;
this.SendPropertyChanged("FK");
this.OnFKChanged();
}
}
}
