小数怎么用Convert.toint转化不成整数了？？？？？？？？

Question

try
{
Response.Write("ToDecimal:"+Convert.ToDecimal("1.11").ToString()+"<br>");
}
catch
{}
try
{
Response.Write("ToDouble:"+Convert.ToDouble("1.11").ToString()+"<br>");
}
catch
{}
try
{
Response.Write("ToInt16:"+Convert.ToInt16("1.11").ToString()+"<br>");
}
catch
{}
try
{
Response.Write("ToInt32:"+Convert.ToInt32("1.11").ToString()+"<br>");
}
catch
{}
try
{
Response.Write("ToInt64:"+Convert.ToInt64("1.11").ToString()+"<br>");
}
catch
{}
try
{
Response.Write("ToUInt16:"+Convert.ToUInt16("1.11").ToString()+"<br>");
}
catch
{}打印结果:
ToDecimal:1.11
ToDouble:1.11整数怎么会报错？？？？？

Answer 1

float s1;
string sb="";
 
sb=string.Format(sb,s1); 
int.Parse(sb);
你这样试试, 应当行!!!

Answer 2

float s1;
string sb="{0}";
 
sb=string.Format(sb,s1); 
int.Parse(sb);

Answer 3

float s1;
string sb="";
 
                            s1=xxx.xx;
sb=string.Format(sb,s1); 
int.Parse(sb);

Answer 4

应该直接用小数转化，不是字符串         
   try
            {
                Console.WriteLine("ToInt32:" + Convert.ToInt32(1.11).ToString());
                Console.ReadLine();
            }
            catch
            {
            }
