createThickness()时如何使用qualifiedDouble？

Question

我需要创建一个6厘米的厚度,我无法设置厘米的大小,我正在看msdn但我不知道如何使用qualifiedDouble

string qualifiedDouble = "6cm";
flowDoc.ColumnWidth = Convert.ToDouble(new Thickness(qualifiedDouble));

我在这做错了什么？谢谢

Answer 1

使用LengthConverter:

LengthConverter lc = new LengthConverter();
string qualifiedDouble = "6cm";

double converted = (double)lc.ConvertFrom(qualifiedDouble);
flowDoc.ColumnWidth = converted;
