方法一：
public float StrToFloat(object FloatString)
{
float result;
if (FloatString != null)
{
if (float.TryParse(FloatString.ToString(), out result))
return result;
else
{
return (float)0.00;
}
}
else
{
return (float)0.00;
}
}
方法二：
public float StrToFloat(object FloatString)
{
try
{
float f = (float)Convert.ToSingle(FloatString);
return f;
}
catch (FormatException)
{
return (float)0.00;
}
}
已见：第一种方法性能比第二种方法好一倍（在dottrace中测试）
