Error Sample:

//假設textBox1.Text等於1.5
textBox1.Text = "1.5";

//轉換textBox1.Text成Double
double a = Convert.ToDouble(textBox1.Text);

//印出結果es錯誤， 語系=en, a=1.5；語系=es, a=15
Response.Write(a.Tostring());

Good Sample:

//假設textBox1.Text等於1.5
textBox1.Text = "1.5";

//轉換textBox1.Text成Double並加上區域文化
double b = Convert.ToDouble(textBox1.Text, System.Globalization.CultureInfo.InvariantCulture)

//印出結果es正確，語系=en, b=1.5；語系=es, b=1.5
Response.Write(b.Tostring());
