如何通過WCF服務和MYSQL插入操作？

Question

我嘗試通過WCF服務創建插入操作。 這是我所做的。 首先，我將向您展示我的項目結構

每個文件說明：

IServiceClient.cs包含服務合同組

[ServiceContract]
public interface IServiceClient
{
    [OperationContract]
    void InsertMaster();
}

Service.cs包含數據合同組

[DataContract]
public class Service
{
    [DataMember]
    public string Id;
    [DataMember]
    public string Submitter;
    [DataMember]
    public string Comments;
    [DataMember]
    public DateTime TimeSubmitted;
}

ServiceClient.cs包含業務邏輯，例如“插入到MYSQL”操作

public void InsertMaster()
{
    string query = "INSERT INTO movies (id, submitter, comments, time) VALUES(id, submitter, comments, time)";
    //open connection
    connection.Open();
    //create command and assign the query and connection from the constructor
    MySqlCommand cmd = new MySqlCommand(query, connection);
    //Execute command
    cmd.ExecuteNonQuery();
    //close connection
    connection.Close();
}

我的問題是，如何將數據協定字段傳遞給ServiceClient.cs，以便我可以編寫一些MYSQL查詢？ 該“字符串查詢”只是我要從數據合同給出的值中插入的演示

我的第二個問題是如何將數據協定字段加載到WCF測試客戶端中？ 在我在客戶端項目中使用它之前，我需要測試它是否可以工作

這是您需要如何修改的：

[ServiceContract]
public interface IServiceClient
{
    [OperationContract]
    void InsertMaster(Service ServiceObj);
}

[DataContract]
public class Service
{
    [DataMember]
    public string Id;
    [DataMember]
    public string Submitter;
    [DataMember]
    public string Comments;
    [DataMember]
    public DateTime TimeSubmitted;
}

public void InsertMaster(Service ServiceObj)
{
    string query = "INSERT INTO movies (id, submitter, comments, time) VALUES(ServiceObj.id, ServiceObj.submitter, ServiceObj.comments, ServiceObj.time)";
    //open connection
    connection.Open();
    //create command and assign the query and connection from the constructor
    MySqlCommand cmd = new MySqlCommand(query, connection);
    //Execute command
    cmd.ExecuteNonQuery();
    //close connection
    connection.Close();

}

使用WCF測試客戶端進行測試后，合同將出現。
