怎么在richTextBox1中显示一个多行三列的的矩阵（数组）

[chunjinyumen]

name定义成一个Array name = new double[125,3];
我现在用this.richTextBox1.AppendText(name + "\n");然后在richTextBox1显示的不规律，有没有什么办法让他的按照原来的规律显示？比如现在我实现的是：
45232.1328070293,56242.1558070293,3.01280702925038,45232.1525672232,56242.1750672232,3.02256722324405,45232.1930031617,56242.1910031617,3.05800316173677,
想做成这样：
45232.1328070293,56242.1558070293,3.01280702925038,
45232.1525672232,56242.1750672232,3.02256722324405,
45232.1930031617,56242.1910031617,3.05800316173677,

string input=@"45232.1328070293,56242.1558070293,3.01280702925038,45232.1525672232,56242.1750672232,3.02256722324405,45232.1930031617,56242.1910031617,3.05800316173677,";
MatchCollection mc=Regex.Matches(input,@"(\d+\.\d+,){3}")

foreach(Match m in mc)
{
   this.richTextBox1.AppendText(m.Value+ "\r\n");
}
