Question

我想知道是否可以为Web服务请求输入参数分配默认值。这是我在wsdl中的输入参数：

<element name="pensionType" default="0" type="int">

在代码方面，我检查了pensionType的值，如下所示：

if (pensionType!=0)
{ TODO code here}
else
{ return warning that no data found}

我在Mozilla Poster中测试了这个。因此，我预计，如果我没有为pensionType提供任何价值，我会收到警告。我收到一个很长的错误：

    System.InvalidOperationException: There is an error in XML document (13, 39). ---> System.FormatException: Input string was not in a correct format.    at

你可以这样做：

if(pensionType != null)
{
    if (pensionType!=0)
    { TODO code here}
    else
    { return warning that no data found}
}

这可能对你有帮助.. !!
