我正在使用自托管创建 WCF 服务。我发现了以下错误,即:
目标程序集不包含服务类型。您可能需要调整此程序集的代码访问安全策略。
代码如下:
namespace MyJobs
{
public interface IJobsSvc
{
[OperationContract]
DataSet GetJobs();
[OperationContract]
Job GetJobInfo(int JobId);
[OperationContract]
List<Job> GetAllJobs();
}
}
namespace MyJobs
{
[DataContract]
public class Job
{
[DataMember]
public int JobId { get; set;}
[DataMember]
public string Description{get;set;}
[DataMember]
public int MinLevel { get; set; }
[DataMember]
public int MaxLevel { get; set; }
}
}
namespace MyJobs
{
public class JobsSvc:IJobsSvc
{
#region IJobsSvc Members
public System.Data.DataSet GetJobs()
{
string str = @"data source=PERSONAL-659BE4;database=practice;integrated security=true";
DataSet ds = new DataSet();
SqlConnection cn = new SqlConnection(str);
SqlDataAdapter da = new SqlDataAdapter("select * from Job1",cn);
da.Fill(ds);
return ds;
}
public Job GetJobInfo(int JobId)
{
string str = @"data source=PERSONAL-659BE4;database=practice;integrated security=true";
SqlConnection cn = new SqlConnection(str);
SqlCommand cmd = new SqlCommand("select * from Job1 where JobId="+JobId,cn);
cn.Open();
SqlDataReader dr = cmd.ExecuteReader();
Job obj = new Job();
if (dr.Read())
{
obj.JobId = JobId;
obj.Description = dr[1].ToString();
obj.MinLevel = Convert.ToInt32(dr[2]);
obj.MaxLevel = Convert.ToInt32(dr[3]);
}
else
{
obj.JobId = -1;
}
return obj;
}
public List<Job> GetAllJobs()
{
throw new NotImplementedException();
}
#endregion
}
}
app.config 文件是:

<compilation debug="true" />
