Function Error

[Rahils573]

Hello Everybody:
I am trying to develop a function to concate three strings . When I compile it gives me a compile error .Can anyone tell me whats wrong?

The error is :
Method 'Project01.Form1.Variable(string, string, string)' referenced without parentheses


public string Variable(string UserName, string PhoneNumber, string RemoteYN)
{
UserName= txtUserName.Text;
PhoneNumber= txtPhoneNumber.Text;
RemoteYN= txtRemoteString.Text;


return Variable= String.Concat( UserName, PhoneNumber, RemoteYN);

I am trying to understand what it is you are doing.

is this the output u are looking for?

UserNamePhoneNumberRemoteYN

Secondly how are you calling this function.

I am looking for the output as

UserName PhoneNumber RemoteYN in a text box.

I am calling the function as :

private void cmdOutPut_Click(object sender, System.EventArgs e)



{ txtOutput.Text=Variable ;

}

}

You have to pass values with the Variable function

In you first posted you showed the function as having three parameters so unless you write a function with no parameters you must pass values. For example

txtOutput.Text = Variable(string1, string2, string3);

plus concat joins the strings together it does not add spaces between the values for you.

why not do

txtOutput.Text = txtUserName.Text + " " + txtPhoneNumber.Text + " " + txtRemoteString.Text;

I tried what u suggessted but it still giving me a error : Says not all code return a value..

Project01.Form1.Variable(string, string, string)': not all code paths return a value


Gives error when I define

public string Variable string UserName, string PhoneNumber, string RemoteYN)




public string Variable(string UserName, string PhoneNumber, string RemoteYN)
{
UserName= txtUserName.Text;
PhoneNumber= txtPhoneNumber.Text;
RemoteYN= txtRemoteString.Text;
}



private void cmdOutPut_Click(object sender, System.EventArgs e)

{ txtOutput.Text= Variable(UserName,PhoneNumber,RemoteYN);

txtOutput.Text = txtUserName.Text + " " + txtPhoneNumber.Text + " " + txtRemoteString.Text;

public void Variable(string UserName, string PhoneNumber, string RemoteYN)
{ 
UserName= txtUserName.Text;
PhoneNumber= txtPhoneNumber.Text;
