Convert a number into the hex value in .NET
(2 answers)
Closed 6 years ago.
I've got a simple question i have got a long value presented in this way
long value = 0x001f0347
Now is there's a way to convert it to string that looks the same:
string value = "0x001f0347";
I have tried some converters but no luck.
Try formatting ("x8" format string - 8 hexadecimal digits):
long value = 0x001f0347;
string result = "0x" + value.ToString("x8");
If you prefer Convert then convert using toBase == 16 and pad left up to 8 symbols
string result = "0x" + Convert.ToString(value, 16).PadLeft(8, '0');

I have got the string like in hex view
33-35-34-37-36-32-31-31-32-35-32-31-32-38-38
I would like to get it like a string of corresponding values
354762112521288
I see it could be done like here
So I am wondering which methods I have to use for it?
I try this for the first value is 33
string hex = "0x33";
int intValue = Convert.ToInt32(hex, 16);
but It gives me 51 instead of 3.
Thanks for helping!
I think,
The hex value for 3 is "3"
"0x33" is 51 in decimal

Add zero-padding to a string

I have a very simple Question to ask.
I have a string like:
string str="89";
I want to format my string as follow :
str="000089";
How can i achieve this?
Assuming the 89 is actually coming from another variable, then simply:
int i = 89;
var str = i.ToString("000000");
Here the 0 in the ToString() is a "zero placeholder" as a custom format specifier; see https://learn.microsoft.com/en-us/dotnet/standard/base-types/custom-numeric-format-strings
If you have a string (not int) as the initial value and thus you want to pad it up to length 6, try PadLeft:
string str = "89";
str = str.PadLeft(6, '0');
If you want the input to be a string you'll have to parse it before you output it
int.Parse(str).ToString("000000")

How to convert numbers between hexadecimal and decimal
(20 answers)
Closed 7 years ago.
My string is in "abcd123ef" format. I want it to convert in long format like in variable b.
I tried many ways but got exception as 'input string is not in correct format'
Ways I tried are shown below:
1)
var a = "ABCD123Ef";
long b = convert.int64(a);
2)
var a = 'ABCD123Ef';
long b = parse.int64(a);
3)
long b = convert.int64("ABCD123Ef");
If that is a hex value you can convert like this
var b = Convert.ToInt64 (a, 16);

I need to be able to take a hexadecimal string and convert it into actual hexadecimal value in .NET. How do I do this?
For instance, in Delphi, you can take string of "FF" and add the dollar sign as follow to it.
tmpstr := '$'+ 'FF';
Then, convert tmpstr string variable into an integer to get the actual hexidecimal. The result would be 255.
Assuming you are trying to convert your string to an int:
var i = Int32.Parse("FF", System.Globalization.NumberStyles.HexNumber)
Your example 1847504890 does not fit on an int, however. Use a longer type instead.
var i = Int64.Parse("1847504890", System.Globalization.NumberStyles.HexNumber)
Very simple:
int value = Convert.ToInt32("DEADBEEF", 16);
You can do it by following
string tmpstr = "FF";
int num = Int32.Parse(tmpstr, System.Globalization.NumberStyles.HexNumber);
You can also see the link Converting string to hex
int hexval = Convert.ToInt32("FF", 16);
