Skip record based on single column value without iterating through each row openxml c#

I am having excel file like following structure:
ColA | ColB | ColC | ColD | ColE | ColF | ColG
1 | a | a | 23 | 12 | asd | 5
2 | s | v | 73 | 14 | qsd | 7
4 | t | b | 52 | 52 | avn |
2 | y | t | 13 | 71 | asx | 2
5 | d | e | 20 | 18 | vss |
1 | f | n | 63 | 72 | ann |
9 | g | a | 27 | 10 | aqz | 15
I want to read and get only those rows which does not have value in ColG.
I can iterate every rows and match each cell value of every row using following code:
for (int i = 0; i < rows.Count(); i++)
{
DataRow dataRow = dataTable.NewRow();
int cellCounter = 0;
foreach (Cell cell in rows.ElementAt(i))
{
dataRow[cellCounter] = GetCellValue(spreadSheetDocument, cell);
cellCounter++;
}
dataTable.Rows.Add(dataRow);
}
But it is very memory and time consuming process.
Can anyone help me out to achieve the same.
Thanks in advance.

How to use "Group by" LINQ?

i use Linq with DataSet for excel multi sheet.

/*== How to use Group by LINQ? ==*/
DataSet dsTmp = new DataSet();
DataTable dtTmp = dtExport.Copy();
var grouped = from table in dtTmp.AsEnumerable()
group table by new { date_Col = table["date"] , code_Col = table["code"] } into groupby
select new

/*== How to use Group by LINQ? ==*/
foreach (var key in grouped)

Thanks advance. :)

You can use like this
var results = from p in persons
group p.car by p.PersonId into g
select new { PersonID = g.Key, Cars = g.ToList() };

How do I insert data in Excel into database

I have been beating my head on this for awhile, this is in import form, it imports lines from a excel spreadsheet to a datagridview then allows the user to make sure changes if needed, then adds or updates the db lines.
I have included sample rows from the spreadsheet, and the part of the code that checks the lines. My issue is that 4 of the rows do not flag as prev. found no matter how many times you run it.
Any input?

The attached file represents a tree structure, that I want to convert into java source code, representing the tree as nested if statements
STOP_WORDS > 0
| NEXT_TYPE > 5: X
| NEXT_TYPE <= 5: Y
STOP_WORDS <= 0
…
If (STOP_WORDS > 0)
{
If (NEXT_TYPE > 5)
{
Return X
}
If ( NEXT_TYPE <= 5)
{
Return Y
}
}
If (STOP_WORDS <= 0)
{
….
}
As you can see, the indentation level using pipe ( | ) symbols represents the parent-child relationship
You can write this program in Java, or if you prefer in any other language you find suitable.
Below is the text file that I need to convert into If statements:
STOP_WORDS > 0
| NEXT_TYPE > 5: 5
| NEXT_TYPE <= 5: 1
STOP_WORDS <= 0
| STREET_TYE > 0
| | PREVIOUS_TYPE > 5: 2
| | PREVIOUS_TYPE <= 5
| | | NEXT_TYPE > 5: 2
| | | NEXT_TYPE <= 5: 5
| STREET_TYE <= 0
| | PERSON_TITLE > 0
| | | NEXT_TYPE <= 5: 4
| | | NEXT_TYPE > 5: 5
| | PERSON_TITLE <= 0
| | | SURNAME > 0
| | | | PREVIOUS_TYPE <= 4: 3
| | | | PREVIOUS_TYPE > 4: 5
| | | SURNAME <= 0
| | | | FIRST_NAME > 0
| | | | | NEXT_TYPE <= 5: 0
| | | | | NEXT_TYPE > 5: 5
| | | | FIRST_NAME <= 0
| | | | | TOKEN_LENGTH <= 1
| | | | | | NEXT_TYPE <= 4: 0
| | | | | | NEXT_TYPE > 4
| | | | | | | NEXT_TYPE <= 5: 1
| | | | | | | NEXT_TYPE > 5: 5
| | | | | TOKEN_LENGTH >1
| | | | | | NEXT_TYPE > 4: 5
| | | | | | NEXT_TYPE <= 4: 0
| | | | | | | PREVIOUS_TYPE <= 1: 4
| | | | | | | PREVIOUS_TYPE >1
| | | | | | | | PREVIOUS_TYPE >3: 4
| | | | | | | | PREVIOUS_TYPE <= 3: 5
My problem is I don't find a logic to keep track of previous If statements and when to close them. As you can see each line has many pipes(|) and sometime less pipe and sometimes more pipes. I don't find the logic for it.
Any help would be appreciated.

Python
with open('input.txt') as f:
indent = 8
prev_depth = -1
closes = []
for line in f:
line = line.strip()
if not line: continue
depth = line.count('|')
while prev_depth >= depth:
prev_depth -= 1
print(closes.pop())
pad = ' ' * (depth*indent)
print(pad + 'If ({})'.format(line.lstrip('| ').split(':', 1)[0]))
print(pad + '{')
closes.append(pad + '}')
if ':' in line:
pad2 = ' ' * ((depth+1)*indent)
print(pad2 + 'Return {}'.format(line[line.find(':')+1:].strip()))
prev_depth = depth
while closes:
print(closes.pop())

Your question is super unclear, but here's a start
barometer = 0
with open('path/to/input') as infile:
for line in infile:
barometer += delta
line = ''.join(itertools.dropwhile(lambda c: c in ' |', line))
if ":" in line:
cond, act = line.split(":",1)
print "If (%s) { Return %s }" %(cond, act)
else:
delta = barometer - sum(1 for i in itertools.takewhile(lambda c: c in ' |', line))
if delta < 0:
print " {}"[delta/abs(delta)]*abs(delta)
print "If (%s) {" %cond
I have to go to sleep now, but this should get you started, at the very least

To convert the above data into unordered list based on depth, I'm using the following code
int lastDepth = -1;
int numUL = 0;
StringBuilder output = new StringBuilder();
foreach (DataRow row in ds.Tables[0].Rows)
{
int currentDepth = Convert.ToInt32(row["Depth"]);
if (lastDepth < currentDepth)
{
if (currentDepth == 0)
{
output.Append("<ul class=\"simpleTree\">");
output.AppendFormat("<li class=\"root\"><span>root</span><ul><li class=\"open\" ><span><a href=\"#\" title={1}>{0}</a></span>", row["name"],row["id"]);
}
else
{
output.Append("<ul>");
if(currentDepth==1)
output.AppendFormat("<li><span>{0}</span>", row["name"]);
else
output.AppendFormat("<li><span class=\"text\"><a href=\"#\" title={1}>{0}</a></span>", row["name"], row["id"]);
}
numUL++;
}
else if (lastDepth > currentDepth)
{
output.Append("</li></ul></li>");
if(currentDepth==1)
output.AppendFormat("<li><span>{0}</span>", row["name"]);
else
output.AppendFormat("<li><span class=\"text\"><a href=\"#\" title={1}>{0}</a></span>", row["name"], row["id"]);
numUL--;
}
else if (lastDepth > -1)
{
output.Append("</li>");
output.AppendFormat("<li><span class=\"text\"><a href=\"#\" title={1}>{0}</a></span>", row["name"],row["id"]);
}
lastDepth = currentDepth;
}
for (int i = 1; i <= numUL+1; i++)
{
output.Append("</li></ul>");
}
myliteral.text=output.ToString();
But the resulting unordered list doesnt seem to be forming properly(using which i am constructing a tree).For example "Site Help" with id '180' is supposed to appear as a direct child of "Televisions" with id '1',is appearing as a direct child of 'Flash' with id '191' using my code.so in addition to considering depth,I've decided to consider itemid as well in order to get the treeview properly.Those rows of the table with itemId not equal to null are not supposed to have a child node(i.e.,they are the leaf nodes in the tree) and all the other nodes can have child nodes.
Please could someone help me in constructing a proper unordered list based on my depth,itemid columns?
Update:
The 'itemid' column refers to the id of an item which is present in another table.This column just helps in identifying if an item has any sub items(i.e., 'name' in my data in this case has any other unordered lists under it).

It looks like the initial code wasn't taking account of the number of levels back up you needed to go from the "Can you tell me more" node to the "Site Help" node.
int lastDepth = -1;
int numUL = 0;
StringBuilder output = new StringBuilder();
foreach (DataRow row in ds.Tables[0].Rows)
{
int currentDepth = Convert.ToInt32(row["Depth"]);
if (lastDepth < currentDepth)
{
if (currentDepth == 0)
{
output.Append("<ul class=\"simpleTree\">");
output.AppendFormat("<li class=\"root\"><span>root</span><ul><li class=\"open\" ><span><a href=\"#\" title={1}>{0}</a></span>", row["name"], row["id"]);
}
else
{
output.Append("<ul>");
if (currentDepth == 1)
output.AppendFormat("<li><span>{0}</span>", row["name"]);
else
output.AppendFormat("<li><span class=\"text\"><a href=\"#\" title={1}>{0}</a></span>", row["name"], row["id"]);
}
numUL++;
}
else if (lastDepth > currentDepth)
{
//output.Append("</li></ul></li>");
output.Append("</li>");
for (int i = lastDepth; i > currentDepth; i--)
{
output.Append("</ul></li>");
}
if (currentDepth == 1)
output.AppendFormat("<li><span>{0}</span>", row["name"]);
else
output.AppendFormat("<li><span class=\"text\"><a href=\"#\" title={1}>{0}</a></span>", row["name"], row["id"]);
numUL--;
}
else if (lastDepth > -1)
{
output.Append("</li>");
output.AppendFormat("<li><span class=\"text\"><a href=\"#\" title={1}>{0}</a></span>", row["name"], row["id"]);
}
lastDepth = currentDepth;
}
