String Functions

[RazSam]

I am trying to format a .dat file which has "" characters in it, example hello, i would like to return "Hello" only.

I am trying to use the replace string function but no joy, i have a for loop to read through the text and when it encounters a "" i am trying to delete it as:

am i doing this the right way?

for (i =0; i<text.Length;i ++)
{
string = text.substring( i,1);
if (string == "")
string.replace( "", "");
}

Thanks

Hai,,

check this code..
It may help you.

string ex="hello ";
string ex1 = string.Empty;
for (int i =0; i<ex.Length;i++ )
{
if ( ! (ex[i].ToString() == ""))
{
ex1 += ex[i];
}

}
MessageBox.Show (ex1.ToString() );

I would recomend that you read the file in as Byte[] (Since it's a binaryfile?)
And then use System.Text.Enc oding.ASCII.Get String() on the byte array.
It should successfully remove all non-standard ascii characters out and return a string with only the text.

Another soultion would be to take that Byte[] and itterate through each index. If the value is withen allowable ASCII character ranges (Check an ASCII chart) you can cast it as a CHAR and add it to a string.

Thanks DKn, i cant understand these characters are from a Unix .Dat file and i cant ger rid of them

Well, try this:

Byte[] mybuf=new Byte[0];

//insert the code here to read in the .DAT file into a Byte[] 
//and store it in the mybuf varriable

string mystring=System.Text.Encoding.ASCII.GetString(mybuf,0,mybuf.Length);

That was great thanks sorry about the late reply
