convert RGB int value to Hex format with 0x prefix in c#

I am trying to convert an RGB value to hex format in c# using this code :

int ColorValue = Color.FromName("mycolor").ToArgb();
string ColorHex = string.Format("{0:x6}", ColorValue);

The colorHex value likes this format ffffff00 but i need to change it like this :0x0000.how can i do that?

Best regards

I am so new in c# form application .

Just add the 0x part yourself in the format string:

// Local variable names to match normal conventions.

// Although Color doesn't have ToRgb, we can just mask off the top 8 bits,
// leaving RGB in the bottom 24 bits.
int colorValue = Color.FromName("mycolor").ToArgb() & 0xffffff;
string colorHex = string.Format("0x{0:x6}", colorValue);

If you want capital hex values instead of lower case, use "0x{0:X6}" instead.
