compare two datatable in c# - c#

what would be the best way to compare two data table. i populate two data table reading two different xml and now i need to compare and return the difference in terms of datatable.my compare logic was
private DataTable CompareDataTables(DataTable dtFirst, DataTable dtSecond)
{
int result = 0;
bool flag = false;
DataTable dtNoRows = new DataTable();
dtNoRows.Columns.Add("Result");
DataTable dtDiff = new DataTable();
dtDiff.Columns.Add("Field Name");
dtDiff.Columns.Add("Old Value");
dtDiff.Columns.Add("New Value");
DataRow dr = null;
if (dtFirst.Columns.Count == dtSecond.Columns.Count)
{
for (int i = 0; i <= dtFirst.Columns.Count - 1; i++)
{
try
{
DateTime.Parse(dtFirst.Rows[0][dtFirst.Columns[i].ColumnName.ToString()].ToString().Trim());
flag = true;
}
catch (Exception ex)
{
flag = false;
}
if (!flag)
{
if (dtFirst.Rows[0][dtFirst.Columns[i].ColumnName.ToString()].ToString().Trim().ToUpper() != dtSecond.Rows[0][dtSecond.Columns[i].ColumnName.ToString()].ToString().Trim().ToUpper())
{
dr = dtDiff.NewRow();
dr["Field Name"] = dtFirst.Columns[i].ColumnName.ToString();
dr["Old Value"] = dtFirst.Rows[0][dtFirst.Columns[i].ColumnName.ToString()].ToString().Trim();
dr["New Value"] = dtSecond.Rows[0][dtSecond.Columns[i].ColumnName.ToString()].ToString().Trim();
dtDiff.Rows.Add(dr);
}
}
else
{
result = DateTime.Compare(DateTime.Parse(dtFirst.Rows[0][dtFirst.Columns[i].ColumnName.ToString()].ToString()), DateTime.Parse(dtSecond.Rows[0][dtSecond.Columns[i].ColumnName.ToString()].ToString()));
if (result != 0)
{
dr = dtDiff.NewRow();
dr["Field Name"] = dtFirst.Columns[i].ColumnName.ToString();
dr["Old Value"] = DateTime.Parse(dtFirst.Rows[0][dtFirst.Columns[i].ColumnName.ToString()].ToString().Trim()).ToString("MM/dd/yyyy") + " - " + DateTime.Parse(dtFirst.Rows[0][dtFirst.Columns[i].ColumnName.ToString()].ToString().Trim()).ToString("hh:mm:ss");
dr["New Value"] = DateTime.Parse(dtSecond.Rows[0][dtSecond.Columns[i].ColumnName.ToString()].ToString().Trim()).ToString("MM/dd/yyyy") + " - " + DateTime.Parse(dtSecond.Rows[0][dtSecond.Columns[i].ColumnName.ToString()].ToString().Trim()).ToString("hh:mm:ss");
dtDiff.Rows.Add(dr);
}
flag = false;
}
}
}
return dtDiff;
}
my code is working fine but i need to the is there any best way out. please guide me.


you can use LINQ to comparing tables values(two table must have the same structure)
bool flag = false;
if (dtFirst.Columns.Count == dtSecond.Columns.Count)
{
for (int i = 0; i <= dtFirst.Columns.Count - 1; i++)
{
String colName = dtFirst.Columns[i].ColumnName;
var colDataType = dtFirst.Columns[i].DataType.GetType();
var colValue = dtFirst.Columns[i];
flag = dtSecond.AsEnumerable().Any(T => typeof(T).GetProperty(colName).GetValue(T, typeof(colDataType)) == colValue);
}
}


var qry1 = dtDuplicate.AsEnumerable().Select(a => new { SchoolID = a["SchoolMID"].ToString()});
var qry2 = dsValadateSchoolInfo.Tables[1].AsEnumerable().Select(b => new { SchoolID = ["SchoolMID"].ToString() });
var exceptAB = qry1.Except(qry2);
DataTable dtMisMatch = (from a in dtDuplicate.AsEnumerable()
join ab in exceptAB on a["SchoolMID"].ToString() equals ab.SchoolID
select a).CopyToDataTable();

Change for loop to forEach

I am working on a inventory updating program in vs2022 which I am using Gembox Spreadsheet for, It is working right now, but the boss man would like me to try to convert my for loop to a for each loop. The loop is what I am using to update my file.
Current For Loop
public void updateFile(string filename, int range, ItemLine selectedItem, decimal outValue)
{
var fullPath = $".\\Backend Files\\{filename}";
SpreadsheetInfo.SetLicense("FREE -LIMITED-KEY");
var workbook = ExcelFile.Load(fullPath, new CsvLoadOptions(CsvType.CommaDelimited));
var worksheet = workbook.Worksheets[0];
//foreach (var row in worksheet.Rows.Skip(1))
//{
// foreach (var cell in row.AllocatedCells)
// {
// string updateValue =
// if(cell.Value == int.TryParse((int)outValue, out int updateValue))
// {
// }
// }
//}
for (int i = 1; i <= range; i++)
{
var plan = worksheet.Rows[i].Cells[0].Value;
var desc = worksheet.Rows[i].Cells[1].Value;
var csvDescription = plan + " - " + desc;
var platedescription = plan + " - ";
if (selectedItem.ComboDescription == csvDescription)
{
worksheet.Rows[i].Cells[2].Value = selectedItem.Quantity;
}
if (selectedItem.plateDescription == platedescription)
{
worksheet.Rows[i].Cells[1].Value = selectedItem.Quantity;
}
}
workbook.Save(fullPath, new CsvSaveOptions(CsvType.CommaDelimited));
}
I beleive the forEach would look similar to this
private static List<ItemLine> ReadFile(string fileName, string defaultValueDescription)
{
string path = $".\\Backend Files\\{fileName}";
SpreadsheetInfo.SetLicense("FREE -LIMITED-KEY");
var workbook = ExcelFile.Load(path, new CsvLoadOptions(CsvType.CommaDelimited));
var worksheet = workbook.Worksheets[0];
var items = new List<ItemLine>();
items.Add(new ItemLine { Description = defaultValueDescription, Quantity = 0 });
foreach (var row in worksheet.Rows.Skip(1))
{
var cells = row.AllocatedCells;
var il = new ItemLine();
if (cells.Count == 2)
{
il.Description = cells[0].Value?.ToString() ?? "Description Not Found";
il.Quantity = cells[1].IntValue;
}
else if (cells.Count >= 3)
{
il.Plan = cells[0].Value?.ToString() ?? "Plan Not Found";
il.Description = cells[1].Value?.ToString() ?? "Description Not Found";
il.Quantity = cells[2].IntValue;
}
items.Add(il);
}
return items;
}

if (testObj.TryGetValue("player", out Newtonsoft.Json.Linq.JToken token)) {
string yourString = token.Value<string>("FirstName"); // can be null
int? yourNullableInt = token.Value<int?>("AnyNumber"); // can be null
int yourInt = token.Value<int?>("AnyNumber") ?? 0; // can be 0 if null
int yourInt = token.SelectToken("firstLayer")?.SelectToken("secondLayer")?.Value<int?>("anyNumber") ?? 0; // return value by path
}
SelectToken is also applicable on Newtonsoft.Json.Linq.JObject.

insert only new data instead duplicate the existing data

//string datas = (ent.Execute<string>(u)).FirstOrDefault();
//Exception ex = new Exception(datas);
throw ex;
}
}
When SaveChanges run, if the data exist it will duplicate the entire row,
How to avoid the data being duplicate when insert (savechanges)??????
Many Thanks

What about: Do not insert.
In these cases I am using a MERGE statement that updates existing data (based on primary key) and inserts new data.
Oh, and all the code example you loved to post is totally irrelevant to the question, which is a pure SQL side question. You literally quote your car manual then asking which direction to turn.

How to update a DataTable created on Main Thread by a new thread in C#?

I have a global DataTable named 'DTImageList' and an XtraGrid named 'uxImageGrid'. Now there is a Method named 'prcFillImagesVideosAndFiles' in which we bring image data from data base page wise i.e. say 500 rows at a time and we create mannual Pages on top of the Grid by using XtraTabControl depending on the total count of data exists according to search. Say if we get 700 Images then will load only 500 at a time and 2 pages will be created as 'Page 1', 'Page 2'.
But in 'prcFillImagesVideosAndFiles' method, we are not fetching the actual images but only its name, id etc. After this I created a new Thread and invoking a method runner which in turn calls a new method called 'FillImages' in which I look through DTImageList and bring actual image one by one from backend and update row with this image due to which XtraGrid starts showing images one by one.
This process works fine for few minutes i.e. loads 20-25 images and after that it gives 'Cross-thread operation not valid' error.
// My prcFillImagesVideosAndFiles method's Code is:
`if (DTImageList != null)

You can try inserting images before you pass it as Datasource to uxImageGrid.
Add image column to DTImageLis.
DTImageList.Columns.Add("Image", typeof(System.Drawing.Image));
Add the image to datatable based on Name,Id etc and bind it to uxImageGrid
uxImageGrid.Datasource=DTImageList;
