我实际上是在搜索guidline,如何在C#-DLL中的公共方法中记录多个异常。
示例:
/// <summary>
/// This method does something
/// </summary>
/// <param name="p_Parameter1">First parameter</param>
/// <param name="p_Parameter2">Second parameter</param>
/// <param name="p_Number">A number</param>
/// <exception cref="ArgumentNullException">
/// Thrown if p_Parameter1 is null</exception>
/// <exception cref="ArgumentNullException">
/// Thrown if p_Parameter2 is null</exception>
/// <exception cref="ArgumentNullException">
/// Thrown if any element of p_Parameter2 is null</exception>
/// <exception cref="ArgumentOutOfRangeException">
/// Thrown if p_Number is below or equal 0</exception>
/// <returns>A object</returns>
public static object DoSomething(
object p_Parameter1, IList<object> p_Parameter2,
object p_Parameter3, int p_Number)
{
if(p_Parameter1 == null)
throw new ArgumentNullException(
paramName:"p_Parameter1",
message:"Parameter is needed");
if (p_Parameter2 == null)
throw new ArgumentNullException(
paramName: "p_Parameter2",
message: "Parameter is needed");
for (int i = 0; i < p_Parameter2.Count; i++)
{
if(p_Parameter2[i] == null)
throw new ArgumentNullException(
paramName: String.Format("p_Parameter2[{0}]", i),
message: "All elements have to be initialized");
}
if(p_Number < 0)
throw new ArgumentOutOfRangeException(
paramName: "p_Number",
message: "Parameter should be bigger then zero");
var returnValue = new object();
// do something where p_Parameter3 == null is allowed
return returnValue;
}
这是记录这些例外的正确方法吗?我应该为每种情况添加一个异常标记,还是应该只为所有不允许空值的参数添加一个?
/// <exception cref="ArgumentNullException">
/// Thrown if p_Parameter1, p_Parameter2
/// or any element of p_Parameter2 are null</exception>
答案 0 :(得分:4)
我肯定会按类型对异常进行分组,即Thrown if p_Parameter1, p_Parameter2
or any element of p_Parameter2 are null
。
作为参考,请查看MSDN上的文档。 example:
ArgumentNullException | Either path, contents, or encoding is null.
