Hi!

From back end I'm fetching 250 records of contractors and storing in each separate string builder using string builder I'm append the data to the array list from these generating the file format.

Here I'm struggling with some problem that is unwanted space is displaying in between the word (or) end of the word (or) starting of the word, this issue is occurring in the every 13th record of the file and in db there is no spaces.

Kindly any one can help me.

I think there is a space from where you read that data..see it carefully..if not then let us know..

Can you tell how are you fetching these records in string builder.
I think appending is not done correctly .

surikarthi 9-Oct-12 8:07am

no its appending to string builder in correct way .

first i'm fetching data from db to the temporary table and from that defining to the business object(BO) using BO I'm appending to the string builder.

which method are you using for appending is it Append or AppendLine?

surikarthi 10-Oct-12 1:29am

here i'm not using any properties of the string builder. using business object(i.e BO) i'm assigning to the string builder .

ex:

just I'm giving only word (i.e contractorsurname). and how I'm displaying in the text file.

StringBuilder contractorsurname = new StringBuilder(previewbo.Surname);

In above line "contractorsurname" is obj of String builder and "previewbo.Surname" this is BO its having data from db

for (int i = 0; i < 30; i++)
{
contractorsurname.Length = 30;
charsurname[i] = Convert.ToChar(contractorsurname[i]);
}

here charsurname[i] is the object of the char Arraylist, from string builder object we are assigning data to the array list and data should be 30 character so i have given limit i less than 30.

st.BaseStream.Seek(0, SeekOrigin.begin);
st.Write(charsurname, 0, contractorsurname.Length);

using above line I'm transferring data to the text file.

No, problem is not by record bcoz
every time it shows space in 82 line 56 position if i have been change the record also.

i have pasted some code how its writing to file

FileStream fs = new FileStream(AttachfileName, FileMode.Create);
//stream writer is used to write text.
StreamWriter st = new StreamWriter(fs);
st.BaseStream.Seek(0, SeekOrigin.Begin);
st.Write(dta, 0, illegal.Length);
st.BaseStream.Seek(3, SeekOrigin.End);

st.BaseStream.Seek(0, SeekOrigin.Current);
st.Write(contractoridentity, 0, contractoriden.Length);
st.BaseStream.Seek(4 - (contractoriden.Length), SeekOrigin.End);

st.BaseStream.Seek(0, SeekOrigin.Current);
st.Write(incometype1, 0, incometype.Length);
st.BaseStream.Seek(1 - (incometype.Length), SeekOrigin.End);

st.BaseStream.Seek(0, SeekOrigin.Current);
st.Write(chartfn, 0, tfn.Length);
st.BaseStream.Seek(9 - (tfn.Length), SeekOrigin.End);

st.BaseStream.Seek(0, SeekOrigin.Current);
st.Write(chardob, 0, contractordfb.Length);
st.BaseStream.Seek(8 - (contractordfb.Length), SeekOrigin.End);

st.Close();
fs.Close();

Why on earth are you doing with this code? Where are your fields coming from and how do you want to format them? I am pretty sure, you have not taken the correct way to do what you want.

Swinkaran 22-Aug-12 2:29am

If you reading from a text file, then it is very easy to manipulate the test file with "TextReader" class rather than using stream. see here http://msdn.microsoft.com/en-us/library/system.io.textreader.aspx

Solution 2

Have you tried with Trim[^], which eliminates leading and trailing whitespace.

Refer More:

Have a look on detailed description on MSDN:

This helped me more than any other codes in Google and simple toooooo,
"
try
{
string[] lines = System.IO.File.ReadAllLines(path);
for (int j = 0; j < lines.Length; j++)
{
lines[j] = lines[j].Replace(" ", "");
Console.WriteLine(lines[j]);
}
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
"
