String to integer conversion

Hello!

Class int has a method for conversion numeric values to strings (ToString() method). Is there any similar method or function, which converts a string into Int32 type?

Cheers!static method System.Int32.Parse()
Thanks!
Hello!

I tried to use the method you gave me, but got an error message: "System.FormatException: Input string was not in a correct format."
Maybe there is any special way I should use it?

Here's how I do it:

void Fill_End_Day(int auto, int aasta, int kuu, int paev) {
 autorent.broneering wsProxy = new autorent.broneering();
 System.Data.DataSet ds;
 ds = wsProxy.JargmineHyiv(auto, aasta, kuu, paev);
 int i;
 for (i=paev; i<System.Int32.Parse(ds.Tables[0].Rows[0]["paev"].ToString()); i++)
 DropDownList7.Items.Add(i.ToString());
 }

Is there something wrong with it?

Cheers.
c# doesn't have cInt()?
I'm afraid it doesn't. Maybe there is some similar function, but I can't even assume in which class I should seek for it.
Sorry, it works now! It should have worked from the beginning, but there has been a stupid mistake in another palce.
Thank you!

string to string[]

string[] strArray;while(dtardrUsrDet.Read())

{

string strUsrEmail=dtardrUsrDet.GetValue(0).ToString();

int intDayDiff=System.Convert.ToInt16(dtardrUsrDet.GetValue(1).ToString());

if(intDayDiff==45)

{

strArray=strUsrEmail;

}

if(intDayDiff==30)

{

strArray=strUsrEmail;

}

how to store string values from reader into string array

Hi,

I am assuming that you want each string in an array, not each character as a separate string in a string array here...

The easiest way is to create an ArrayList, add each string to that (within a while loop to read each record from the DataReader) and then use the ToArray() method, passing the type that you want the array to be (i.e string in your case).

In .net 2.0, you would use a generic List<string> collection, which gives you the advantage of strong typing on the collection.

Rich

string[] strArray;

Int i=0;

while(dtardrUsrDet.Read())

{

string strUsrEmail=dtardrUsrDet.GetValue(0).ToString();

int intDayDiff=System.Convert.ToInt16(dtardrUsrDet.GetValue(1).ToString());

if(intDayDiff==45 ||intDayDiff==30)

{

Array.Resize(refstrArray, i);
strArray[i] =strUsrEmail;

i++;

}

}

hope this helps./.

String -tostring

hi

what is actually difference between string and To string?when it used in which condition?

Hi,

String is a type whileToString() is a method on the Object class.

Grz, Kris.

Ok, XIII. I agree with you

I'm surethat's a relief.

string.Split() does not work?

The following code:

string strProductIDAndProductCategory = Convert.ToString(e.CommandArgument); // productidandproductcategory sent in the command argument
string [] strArrayProductIDAndProductCategory = strProductIDAndProductCategory.Split("/");

...gives me the following compile error:
The best overloaded method match for 'string.Split(params char[])' has some invalid arguments

What are these 'invalid arguments'?

when i change it from Split("/") to Split() it works just fine... what gives?

thanks"/" is a string and not a char[]

Try this

char[]splitOn = {'/'};
string [] strArrayProductIDAndProductCategory = strProductIDAndProductCategory.Split(splitOn);

or this

string [] strArrayProductIDAndProductCategory = strProductIDAndProductCategory.Split('/');

String/Number manip.

In the following line:
txtWage.Text = "$" & Trim(dataReader.GetValue(9).ToString)

It returns $20.0000 I only want it to return back $20.00 -- every search I've done in string manip. has shown me zilch.

Any suggestions?

txtWage.Text = Format(CDbl(Trim(dataReader.GetValue(9).ToString)), "currency")
I think you can use String.Format also to do the same thing, with the format of {0:c}

StringBuilder to Text

Hello, I a m building an email message in a StringBuilder Object and then
using the StringBuilder ToString() method to get it to regular text. It
appears to me that when I place a "\n" into the Stringbuilder object that
when this is translated into text, I loose the page break. Is this true and
I doing something wrong?
I'm guessing that I could insert a special character into the StringBuilder
object and then use the string Replace() method to translate that special
character into a "\n" and perhaps this would work.
Just wondering why it does not work when I place that value into the
StringBuilder Object.
ThanksHow are you noticing that you loose the break? In what context is this
happening?

Have you considered using Environment.Newline instead of "\n"?
Example:
StringBuilder textBuilder = new StringBuilder(512);
textBuilder.Append("Dear John,");
textBuilder.Append(Environment.Newline)
Perhaps that will help.

Try Environment.NewLine

I am loosing the page break when I use the StringBuilder ToString() method
when I am formatting an email message. I will try the Environment.NewLine()
method and see if that retains the line break.
Does the StringBuilder cause the newline disappear, or is it something with
the mail component. What happens if you just set the
StringBuilder.ToString() to a variable and looked at it, is the newline
gone?

I assume you are using c?
If you pass "\n" you'll get newline > chr(10)
If you want "\n" you might consider to use "\\n"
(Outlook express mangels this for me, use slash twice)
