Zmień tekstowe BackColor w kodzie-za

Question

Jak mogę zmienić pole tekstowe BackColor w code-za coś takiego:

Textbox1.BackColor = "#F2F0E1 

zamiast

Textbox1.BackColor = System.Drawing.White 

Answer 1

Można spróbować czegoś takiego:

Textbox1.BackColor = System.Drawing.ColorTranslator.FromHtml("#F2F0E1"); 

Answer 2

Utwórz funkcję, aby uzyskać kolor z ciągu szesnastkowego

---

public Color HexColor(String hex) 
    { 
    //remove the # at the front 
    hex = hex.Replace("#", ""); 

    byte a = 255; 
    byte r = 255; 
    byte g = 255; 
    byte b = 255; 

    int start = 0; 

    //handle ARGB strings (8 characters long) 
    if (hex.Length == 8) 
    { 
     a = byte.Parse(hex.Substring(0, 2), System.Globalization.NumberStyles.HexNumber); 
     start = 2; 
    } 

    //convert RGB characters to bytes 
    r = byte.Parse(hex.Substring(start, 2), System.Globalization.NumberStyles.HexNumber); 
    g = byte.Parse(hex.Substring(start+2, 2), System.Globalization.NumberStyles.HexNumber); 
    b = byte.Parse(hex.Substring(start+4, 2), System.Globalization.NumberStyles.HexNumber); 

    return Color.FromArgb(a, r, g, b); 
    } 

ustaw

Color c = HexColor("#F2F0E1"); 

Textbox1.BackColor = HexColor("#F2F0E1"); 

OR

Textbox1.BackColor = c;
