    Hi I've begun learning C# and begun writing some code that would normally work in C and C++: protected void Button1_Click(object sender, EventArgs e) { char[] text1,text2; int ii=0; text1 = TextBox1.Text.ToCharArray(); while (text1[ii]!= 0) { //text2.[ii] = caract; text2[ii] = text1[ii]; ii++; } text2[ii] = 0; ****** TextBox2.Text = text2.ToString(); } This won't compile and for the line ****** return the error: Constant value '0' cannot be converted to a 'char' I've tried to assign it to null, "" , '', but none of them work. thanks NYB

    you may need ChrW(0) or Chr(0) and for while condition maybe Asc(text1[ii])>0

    *remember that conversion between char and integer is not automatic*
