Unable To Get The Content Of The Text File Saved In The Database(My-Sql)

Apr 4, 2011

In my MySql i am having my data field as longblob i would like to get the content in that file so i have written my code as follows

This is what i am doing before inserting

string filePath = Server.MapPath("AchTemplates/genACH.txt");
string filename = Path.GetFileName(filePath);
FileStream fs = new FileStream(filePath, FileMode.Open, FileAccess.Read);
BinaryReader br = new BinaryReader(fs);
Byte[] bytes = br.ReadBytes((Int32)fs.Length);
br.Close();
fs.Close();
string strQuery = "insert into tblFiles(FName,FData) values (@_FName, @_FData)";
MySqlCommand cmd = new MySqlCommand(strQuery);
cmd.Parameters.Add("@_FName", MySqlDbType.VarChar).Value = filename;
cmd.Parameters.Add("@_FData", MySqlDbType.LongBlob).Value = bytes;
InsertUpdateData(cmd);
//Get Data
private void download(DataTable dt)
{
Byte[] bytes = (Byte[])dt.Rows[0]["FData"];
Response.Buffer = true;
Response.Charset = "";
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.ContentType = dt.Rows[0]["ContentType"].ToString();
Response.AddHeader("content-disposition", "attachment;filename="
+ dt.Rows[0]["Name"].ToString());
Response.BinaryWrite(bytes);
Response.Flush();
Response.End();
}

But i am getting the content as system.string[].

Read Large File Size Text File?

Jan 17, 2011

I have a text file with tab as delimiter. There are about 20 fields in the text file and the file size is about 150MB-200MB.

I need to filter out each row in the textfile based on its field criteria, For Eg: the i should ignore the particular row if the Field A is empty.

I know that by reading out the text file row by row it will be certainly slow.

how to read out the text file fast and also how to do the file processing for the read out text file?

Web Forms :: How To Read From Text File Using C#

Mar 21, 2010

I found some code that looks like it will do what I want to do, but the code doesn't work.

[Code]....

The error seems to occur here: mytext.txt

Error Message is: unrecognized escape sequence

I think somehow the syntax with StreamReader is not quite right.

I did something similar in VB and it worked fine. I'm just beginning to learn C#; it's going to be a little while before the training wheels come off.

How To Set Read Only Property For Text File Through The Code

Mar 31, 2010

I have a txt file, in which read only property is true. When I try to write some text in that file through the vb coding, it's through the error. I have shown the code below.

Dim fs As FileStream = File.OpenWrite(HttpContext.Current.Server.MapPath("Include/CacheKeyFile.txt"))
Dim sw As New StreamWriter(fs)
sw.Write("Menu setup updated by " & value & " on " & DateTime.Now.ToString())
sw.Close()
fs.Close()

I found the cause of the error. If we set the Write access property to false, we can open the file and write it without showing the error messages.

I need to remove the Read only property for a file through the vb. Net code. Is it possible? Can we set the read only for txt file before open and write operation?
