Convert.ToString(DataReader.GetInt32(2))

Convert.ToString(DataReader.GetInt32(2)) lblReasult.Text = Convert.ToString(c); lblReasult.Text = Convert.ToString(c);什么意思? C#中,Convert.ToString(a)与a.ToString()的区别是? toString(). toString(). c#中 Double num1 = Convert.ToDouble(this.textBox1.Text.ToString())是什么意思, HiddenField1.Value = (Convert.ToInt32(HiddenField1.Value) + 1).ToString();啥意思?加1啥意思 private void button16_Click(object sender,EventArgs e){switch(s){case+:b = Convert.ToDouble(textBox1); c = a + b; textBox1.Text = c.ToString();break;case-:b = Convert.ToDouble(textBox1);c=a-b;textBox1.Text = c.ToString();break;case*:b = Convert c#代码 ApplicationApplication.Set(jilu,Application[jilu] + + Convert.ToString(Session[name]) + 说： + TextBox2.Text); 这代码 什么意思 求解 在线等. C#计算器正负号private void button21_Click(object sender, EventArgs e) { int n = 0; a = Convert.ToDouble(lala.Text); if (n % 2 == 0) { lala.Text = Convert.ToString(-a) 一个语句看不明白,..DateTime dt;dt = DateTime.Now;DateTime dat = Convert.ToDateTime(12/12/1983);Response.Write(dt.Year.GetType() + );在上面的语句里,DateTime dat = Convert.ToDateTime(12/12/1983);这句是什么意思?为什么我 dat是什么意思 dat 是什么意思? dat是什么意思? myDataReader[password].ToString(). c 中tostring()是什么意思 C# 基础语言 if..elsestring tax;decimal taxa;Console.WriteLine(Enter tax Y or N);Input = Console.ReadLine();tax = Convert.ToString(Input);if (tax == Y);{taxa=0.01;}else(tax == N);{taxa=0;}Console.WriteLine(taxa) 题要求输入Y 显示 10输入N
