如何保存字符串路径文件？ [英] How Do I Save A String Path File?

问题描述

您好。我正在创建一些合同并在WCF服务中实现它们。我有以下代码：

Hi. I am creating some contracts and implementing them in a WCF service. I have the following code:

public interface IContent
    {
        [OperationContract]
        bool AddContent(string description, string location, int userID);
    }
    [DataContract]
    public class ContentData
    {
        [DataMember]
        public String Description;

        [DataMember]
        public String Location;
    }

实施方式如下：

It is implemented as thus:

public bool AddContent(string description, string location, int userID)
{
    ...
}

当我在测试中运行服务时客户端，并为位置传递路径，例如：



E：\ My Documents \Content\testcontent.txt



引发错误消息时出现DbEntityValidationException错误：位置字段是必需的。



在调试时，实现中的 location 参数是 null 。



当我尝试时为 location 传递一个普通字符串，而没有路径'\'，例如如果我输入一个诸如这应该工作！之类的值，它可以工作:-( ..



如何解决反斜杠问题？我对什么感到困惑可能是错的。

When I run the service in the test client, and for location pass a path, such as:

E:\My Documents\Content\testcontent.txt

A DbEntityValidationException error is thrown with the Error Message: The Location field is required.

On debugging, the location parameter in the implementation comes in null.

When I try and pass a plain string for location without the path's '\', e.g. if I enter a value such as "This should work!", it works :-(..

How can is solve the backslash problem? I am confused on what could be wrong.

推荐答案

哦..我解决了这个问题。



路径需要转义在测试客户端。

感谢所有相同..： - ）

Oh.. I solved this.

The path needs to be escaped at the test client.
