Notice that
<test><hello>world</hello></test>
is identical to
<test>
<hello>world</hello>
</test>
but it is NOT identical to
<test><hello>
world
</hello></test>

in this case the only solution i can think is load in dataset , as the first answer ... do you have other ideas?

One can use XmlTextReaders instead of the StreamReaders. Also possible but more memory consuming: Load both files into a XmlDocument and compare the strings returned by the InnerXml property.

Hello all,
I'd like to open a console window that is usable with System.Console.ReadLine/WriteLine from a WinForm.
I'm trying to do it by clicking a button, but I'm having difficulty figuring it out.
How do I create / initialize the window?
Also, are there any issues with passing info back and forth between the console window and the form?
Currently, I can get a string to output to the Output window when I click the button, but I want a console. I can also use the process control to call a cmd.exe window, but can't get the IO there...
Thanks in advance.

You might be able to create a cmd.exe process and then use the RedirectStandardInput and RedirectStandardOutput to the streams of the Console class (something like GetStandardInputStream and GetStandardOutputStream from the Console class). You should be able to then write using Console.WriteLine etc and read using Console.ReadLine etc to read and write from cmd.exe.
Note I havn't had the time to look it up properly, but then again that's your job  , still might be useful to me when I get the time.

How to check validation numeric field in C# coz C# doesn't has built-in IsNumeric function 
Angela
|
|
|
|
|
Three ways
1 - use a MaskedEditBox
2 - write your own handler so the edit box only takes numbers
3 - use Char.IsNumber to check all the characters in the string.

ok, thanks

Use this
public bool IsNumeric(string s)<br />
{<br />
try<br />
{<br />
Int32.Parse(s);<br />
}<br />
catch<br />
{<br />
return false;<br />
}<br />
return true;<br />
}<br />

Thanks for your source code
just now i also found another way to validate the numeric field, I would like to share it with you :
public bool chkNumeric(string strText)
{
char[] chars = strText.ToCharArray();
for (int i = 0; i < chars.Length; i++)
{
if (chars[i] > 57 || chars[i] < 48)
{
return false;
}
}
return true;
}

Be careful. The exception police will get you. As has been explained to me, relying on exceptions is bad practice. Use TryParse instead of Parse and it returns a boolean to let you know if it worked or not.

Well you could just do like this:
try
{
Convert.ToInt32(txtstring);
}
catch
{
MessageBox.Show("You must input a numeric value!");
return;
}

And whats about this...
if(!char.IsNumber(e.KeyChar)
e.Handled=true;
write it in the text control's KeyPress event.

A couple of notes about the other replies:
1. You don't want to be catching exceptions as part of the normal logic flow. This is a well-accepted standard in software development.
2. You don't want to do this in a KeyPress event since that won't handle pasting code from another source.
For a more robust equivalent to VB's IsNumeric method see: http://www.tangiblesoftwaresolutions.com/Articles/CSharp%20Equivalent%20to%20IsNumeric.htm[^]

Standard Windows copy/paste doesn't trigger KeyPress events.
User the TextChanged event to capture pasting of text also.

of course! I checked it last day and found the same situation. It means that we can't rely on only keyPress event for validation, we have to check some other events too; like, as you mentioned, TextChanged etc.
Thanks.

this code may help you to check whether the given value is numeric or not
using System.Text.RegularExpressions;
public static bool CheckNumeric(string strText)
{
return CheckRegExPattern(@"^[0-9]+$", strText.Trim());
}

What is this? I didn't find it.

While taking idea from this I tryed to implement it like this:
using System.Text.RegularExpressions;<br />
public bool CheckNumeric(string strtext)<br />
{<br />
System.Text.RegularExpressions.Regex rr = new Regex(@"^[0-9]+$");<br />
return rr.IsMatch(strtext); <br />
}<br />
<br />
MessageBox.Show(this.CheckNumeric(TextBox1.Text).ToString());
Its working, but i'm unable to interpret this @"^[0-9]+$"
Thanks and Best Regards
