Why does my parallel.ForEach method return the wrong values?

I have a large List of objects (over 100k rows in a txt file). I have to do some data work with each item in the list I save the object to the database if it doesnt exist and if it does I increase a number column in the for the item and then update the database while saving the updated item.
If I use a regular foreach loop everything works out fine but it takes over 24 hours to finish.
The issue is that when I use a parallel loop the records do not match and sometimes I will get an error on the .Save() method that the item ID was changed.

I tried using ConcurrentBag instead of List but ran into an issue because ConcurrentBag does not have the FindIndex method (var index = pomList.FindIndex(r => r.ID == _isplacena.ID);). I know there is some way to take out the object and put back in but not sure how to do that and from what I read Lists should be ok if you use locking which I am.
Please help.

How to convert System.Web.Mvc.SelectListItem to list

How to add a Group of data with only one unique group ID using C# in MSSQL?

I want to create a group of registered clients using different products, categories and sub categories.
I am using asp.net C# and updating database using entity model.
int PID = Convert.ToInt32(ddProduct.SelectedValue);
if (isValidName(txtGroupName.Text))
{
if (ddBusinessCategory.SelectedValue == "0")
{
var clients = db.Client_Master.Where(c => c.InquiredFor == PID).ToList();
foreach (var clt in clients)
{
Group_Master gobj = new Group_Master();
gobj.GName = txtGroupName.Text;
gobj.ProductID = PID;
gobj.CatID = null;
gobj.SubCatID = null;
gobj.ClientID = clt.CID;
gobj.CreatedBy = Convert.ToInt32(((User_Master)Session["User"]).UID);
gobj.CreatedOn = DateTime.Now;
db.Group_Master.AddObject(gobj);
db.SaveChanges();
}
}
else
{
if (ddSubCategory.SelectedValue == "0")
{
int CID = Convert.ToInt32(ddBusinessCategory.SelectedValue);
var clients = db.Client_Master.Where(c => c.InquiredFor == PID && c.BusinessCategory == CID).ToList();
foreach (var clt in clients)
{
Group_Master gobj = new Group_Master();
gobj.GName = txtGroupName.Text;
gobj.ProductID = PID;
gobj.CatID = CID;
gobj.SubCatID = null;
gobj.ClientID = clt.CID;
gobj.CreatedBy = Convert.ToInt32(((User_Master)Session["User"]).UID);
gobj.CreatedOn = DateTime.Now;
db.Group_Master.AddObject(gobj);
db.SaveChanges();
}
}
else
{
int CID = Convert.ToInt32(ddBusinessCategory.SelectedValue);
int SID = Convert.ToInt32(ddSubCategory.SelectedValue);
var clients = db.Client_Master.Where(c => c.InquiredFor == PID && c.BusinessCategory == CID && c.SubCategory == SID).ToList();
foreach (var clt in clients)
{
Group_Master gobj = new Group_Master();
gobj.GName = txtGroupName.Text;
gobj.ProductID = PID;
gobj.CatID = CID;
gobj.SubCatID = SID;
gobj.ClientID = clt.CID;
gobj.CreatedBy = Convert.ToInt32(((User_Master)Session["User"]).UID);
gobj.CreatedOn = DateTime.Now;
db.Group_Master.AddObject(gobj);
db.SaveChanges();
}
}
}
Groups();
}
I tried to add Group ID using many ways but didn't succeed.
Please suggest me how can I solve this.
Thank you !!

You should create new table ClientsProducts, which will have reference to Client ID and Product ID. This is called One-to-Many Relationships.
You can read here about this here.

I Solved this by taking the ID of last data of list and save as a group ID so, with the help of this we get unique group ID.
if (ddBusinessCategory.SelectedValue == "0")
{
var clients = db.Client_Master.Where(c => c.InquiredFor == PID).ToList();
int GrpID = 0;
if (clients.Count() > 0)
{
foreach (var clt in clients)
{
if (ProductGrp(PID, clt.CID))
{
Group_Master gobj = new Group_Master();
gobj.GrpID = 0;
gobj.GName = txtGroupName.Text;
gobj.ProductID = PID;
gobj.CatID = null;
gobj.SubCatID = null;
gobj.ClientID = clt.CID;
gobj.CreatedBy = Convert.ToInt32(((User_Master)Session["User"]).UID);
gobj.CreatedOn = DateTime.Now;
db.Group_Master.AddObject(gobj);
db.SaveChanges();
GrpID = gobj.GID;
}
else
{
ScriptManager.RegisterStartupScript(Page, this.GetType(), "myscript()", "bootbox.alert({title: '<b>Error</b>',message: '<b>Group already exist.</b>',});", true);
break;
}
}
List<Group_Master> ggobj = db.Group_Master.Where(g => g.ProductID == PID && g.CatID == null && g.SubCatID == null).ToList();
foreach (var gid in ggobj)
{
if (gid.GrpID == 0)
{
Group_Master gmobj = db.Group_Master.Single(s => s.GID == gid.GID);
gmobj.GrpID = GrpID;
db.SaveChanges();
}
}
}
else
{
ScriptManager.RegisterStartupScript(Page, this.GetType(), "myscript()", "bootbox.alert({title: '<b>Error</b>',message: '<b>No Clients exist.</b>',});", true);
}
}

Insert multiple records in database using parallel.foreach

I am trying to insert around 5000 records in database using foreach loop. It is taking around 10 min which is not acceptable as per the requirement. I also thought about the approach in which first insert the records in a datatable and then converting it into XML pass it to stored procedure which do the insertion. But unfortunately it is not getting fit in my situation. Now i am doing the same thing using parallel.foreach but after inserting 10 records i am getting "Unique constraint violation for the primary key" error msg. As i am new to parallel programming so not getting the solution for it. Below is my code that i have done so for.

Getting error when generating the primary key value using the below function :

Where SR_NO is the primary key in that table.
Any help will be very much appreciated. Thanks in advance.

The fastest way to do such inserts is using ADO.NET, specifically, SQL Bulk Insert. If you're using SQL Server as your database, the relevant code will be something like this:
DataTable dt = GetDataTableFromExcel(excelFile, true);
using (var copy = new SqlBulkCopy(yourConnectionString) //There are other overloads too
{
BulkCopyTimeout = 10000,
DestinationTableName = dt.TableName,
})
{
foreach (DataColumn column in dt.Columns)
{
copy.ColumnMappings.Add(column.ColumnName, column.ColumnName);
}
copy.WriteToServer(dt);
}

Please look at my comment to other question
You could use guid as primary key into your table. It would help you to avoid problem with ##IDENTITY. At first you should generate new guid-identity, thank insert the generated value into a row

However, now I need to be able to change the status and title of a case from C# given its incidentid.
Ive looked at the SDK docs and cannot find an example of this.
Anyone work with this before?
Thanks
Simply put, above is code to read an incident. Could I get an example of writing an incident field, Just one. Ex: How could I change the title of an incident.

You can call the Update method on the CrmService. Here is the SDK article.
Case c = new Case();
c.ID = id;
c.Title = title;
svc.Update(c);

To change the state of an entity you use the setstaterequest. If you want to do it to a dynamic entity there's a description in this blog
