C#怎么解析 java转的16进制图片字符串

Question

如题 我现在有个由java转的16进制图片字符串，我要用C#的方法将其转换，
然后保存图片文件，有哪位大神知道方法，求告知

或者将下面java解析、保存图片的代码转换成可运行的C#代码

public void saveToImgFile(String src, String output)

{

if (src == null || src.length() == 0)

{

return;

}

try

{

src=src.replaceAll("(00){1,}$", "");
FileOutputStream out = new FileOutputStream(new File(output));

byte[] bytes = src.getBytes();

for (int i = 0; i < bytes.length; i += 2)

{

out.write(charToInt(bytes[i]) * 16 + charToInt(bytes[i + 1]));

}

out.close();

}

catch (Exception e)

{

e.printStackTrace();

}

}

private int charToInt(byte ch)  
{  
    int val = 0;  
    if (ch >= 0x30 && ch <= 0x39)  
    {  
        val = ch - 0x30;  
    }  
    else if (ch >= 0x41 && ch <= 0x46)  
    {  
        val = ch - 0x41 + 10;  
    }  
    return val;  
}
