.net - C#: UniCode To String Conversion?
Nov 15, 2010
How can I Convert a Unicode value to its equivalent string for example i have "రమెశ్" and i need a function that accepts this unicode value and returns a string I was looking at the System.Text.Encoding.Convert() function but that does not take in a Unicode value, it takes 2 encodings and a byte array. I bascially have a byte array that I need to save in a string field and then come back later and convert the string first back to a byte array. So i use ByteConverter.GetString(byteArray) to save the byte array to a string but can't get it back to a byte array.

I am trying to update someonelse code, the attached code reads from a unicode txt files and compares a string of "Department_Name |Division_Name|Position_Name|Job_Name" with a db field called "ident_org" in org tbl. Since it is a bad design, I need the code to check a combination of ""Department_Code|Division_Name|Job_Code" against db and get the value of uid_org (unique key). Then if key exists then update that specific row(s) else insert the combination of "Department_Name|Division_Name|Position_Name|Job_Name" into db.[code]....

I'm trying to write a function to find a word in a string in the this format : "ThisissometextthatIneedtofindandthisisthetext. This is another text."It's read as " This is some text that I need to find and this is the text. This is another text." but there is no space between each word. I want to get the word "text" or any word in that string. Can you help me with this function with a code sample ?
And I think that this method can be implemented with a string of Unicode also because in a sentence of Unicode it contains one or few, sometimes zero spaces between each word.

I am getting this datetime format in an xml file:
2012-06-14T11:15:41.587-07:00
2012-06-14T10:49:32.397-07:00
2012-06-11T11:10:49.2-07:00
I believe I understand some of it, please correct me if I am wrong:
2012-06-14 = date
T = time identifier
10:49:32.397 = hour min second milliseconds
-07:00 = I have no idea
I need to convert this to something I can sort on for my datagrid view.
When I try something like this:
Console.WriteLine(String.Format("{0:d/M/yyyy HH:mm:ss}", "2012-06-14T10:49:32.397-07:00"))
I'm getting the original string back out with no conversion.
