此集合已包含方案http的地址.此集合中每个方案最多只能有一个地址.如果您的服务在IIS所驻留你可以通过设置"system.serviceModel/serviceHostingEnvironment/multipleSiteBindingsEnabled"为真或指定"system.serviceModel/serviceHostingEnvironment/baseAddressPrefixFilters"解决问题.参数名称:item描述:执行当前Web请求期间发生未处理的异常.请查看堆栈跟踪以获取有关错误及其源自代码的位置的更多信息.

例外细节:

System.ArgumentException: This collection already contains an address with scheme http.  There can be at most one address per scheme
