Invalid expression term 'out'

[slsv]

Hi, I'm a little bit new in this area and I have this error
Can someone tell me what is this mean? -
Invalid expression term 'out' and
Identifier expected; 'out' is a keyword

public static void userDell(string msi,String filename, String DB_CONN_STRING)
        {
            String temp_msisdn = "+" + msi;
            bool ima = DatabaseConnection.checkExist(temp_msi);
            bool result;
            if (ima) 
            {
                result = DatabaseConnection.deleteRoute(temp_msi);
            }
            System.out.println ("Delete Route " + temp_msi);
            WriteLog.writeLog(filename + "|OK|DELETE|" + temp_msi + "||" + "route deleted||\n", "logs", "1.log");
        }

That line

System.out.println ("Delete Route " + temp_msi);

, did you get that ffrom some Java code somewhere? In C# you use Console.WriteLine instead.

[slsv]

Yes, is part of Java code.
I saw that in Java System.out.println is equivalent to Console.WriteLine in C#.. but when i change it i get more errors.. like:

bool ima = DatabaseConnection.checkExist(temp_msisdn);

'DatabaseConnection' does not exist in current context.

WriteLog.writeLog(...)

'WriteLog' does not exist in current context.

When is a 'System.out.println' i don't have this errors..

[r035198x]

Those errors are there because you didn't import the namespaces that contain those classes. The System.out.println doesn't fix those errors, it just hides them. Don't try to compile Java code using a C# compiler. Write proper C# code importing the required classes with the using clause.

[slsv]

Like I said, I'm a little bit new and I don't know exactly how to rewrite it in C#..
That's why i trying to work with this java piece of code..
I must do this piece of code in my first post to make it work in this condition. How can :

    string[] lines = File.ReadAllLines(@"pathtofile"); 
            foreach (string line in lines)
            {
                string[] columns = line.Split('|');
                string code = columns[2];
                if (code.Equals("D"))
                {
                    mod.userDell);
                    Console.WriteLine("");
                }

Basically read one file and when the flag is "D" must delete from DB

[r035198x]

If you need to write C# code then read a C# tutorial first. You can't just copy code from one language to another without understanding the syntax rules of the target language first.

[slsv]

Ok, thanks for the help.

Hey slsv, till now what did you done with your code? Did you read your file? Did you connected to your database from your C# Program? If connected means, did you checked whether user is already existed or not in your table?

[slsv]

Hey vijya6, till now i successfully connected to database and read from file. So now i need to perform this action in my first post. While i read the file i check for flag "D" and when i have a line with this file I must delete.

[vijay6]

While i read the file i check for flag "D" and when i have a line with this file I must delete.

Hey slsv, what you want to delete?

[slsv]

Whole line and continue to next line.

[vijay6]

Whole line and continue to next line.

Hey slsv, you want to remove whole line only from your file?

[slsv]

it's only one file.. here is the scenario:
1.Connect and take the file.
2.Read the file and split it.
3.While reading the file if the char of this line is "d" i will delete the line and continue on next.

So far i have connection and reading.
I have this what to do if flag is 'D' ( first post ) then in my reading class i put this:

UserMod.UserMod mod = new UserMod.UserMod();

How to call it in here:

if (code.Equals("D"))
                {
                    mod.userDell( // HERE ); <--- HERE 
                    Console.WriteLine("");
                }

[vijay6]

Hey slsv, try this code...

string text = String.Empty;
 
string[] lines = System.IO.File.ReadAllLines(@"pathtofile");
foreach (string line in lines)
{
    string[] columns = line.Split('|');
    string code = columns[2];
    if (!code.Equals("D"))
    {
        text = text + line + Environment.NewLine;
    }
}
 
text = text.Remove(text.Length - 1);
 
System.IO.File.WriteAllText(@"pathtofile", text);

[slsv]

Hey, thanks for this but how this is connected with this

 
    public static void userDell(string msi,String filename, String DB_CONN_STRING)
            {
                String temp_msisdn = "+" + msi;
                bool ima = DatabaseConnection.checkExist(temp_msi);
                bool result;
                if (ima) 
                {
                    result = DatabaseConnection.deleteRoute(temp_msi);
                }
                System.out.println ("Delete Route " + temp_msi);
                WriteLog.writeLog(filename + "|OK|DELETE|" + temp_msi + "||" + "route deleted||\n", "logs", "1.log");
            }
 
 

I want to use this?

[vijay6]

I want to use this?

Upto your wish!!!

public static void userDell(string msi,String filename, String DB_CONN_STRING)
{
    String temp_msisdn = "+" + msi;
    bool ima = DatabaseConnection.checkExist(temp_msi);
    bool result;
 
    if (ima)
    {
        result = DatabaseConnection.deleteRoute(temp_msi);
    }
 
    System.out.println ("Delete Route " + temp_msi);
    WriteLog.writeLog(filename + "|OK|DELETE|" + temp_msi + "||" + "route deleted||\n", "logs", "1.log");
}

Hey slsv, I don't know what 'msi' means here. I assume 'msi' represents name (msi = "slsv"). This code checks whether your table in your database have row(s) with value as 'slsv' (Line number 4). If true (i.e., it have row(s) (Line number 7)) then it deleting all the row(s) which has msi as 'slsv' (Line number 9) and updating that in a textfile as 'slsv' deleted (Line number 13).

I'm sure my answer won't be absolutely right. Ask the person who wrote this code to know what this code is exactly doing...

[slsv]

 
    if (code.Equals("D"))
                    {
                        //mod.userDell( // HERE ); <--- HERE 
                        mod.userDell(columns[0], columns[1]);
                        Console.WriteLine("");
                    }
 
 

[vijay6]

Hey slsv, now you want to remove that line also from your database?

[slsv]

@vijay6,
this is what i needed and now is working:

 mod.userDell(columns[0], columns[1]);
