XMLTask.SecondOperand 属性

定义

命名空间:

Microsoft.SqlServer.Dts.Tasks.XMLTask

程序集:

Microsoft.SqlServer.XMLTask.dll

获取或设置作为使用两个操作数的操作中第二个操作数的连接的名称、变量或用户提供的文本。 根据所执行的操作，第二个操作数可以是 XML 文档、DiffGram、XSLT、XPath 或验证文档。

public:
 property System::String ^ SecondOperand { System::String ^ get(); void set(System::String ^ value); };

public string SecondOperand { get; set; }

member this.SecondOperand : string with get, set

Public Property SecondOperand As String

属性值

String

包含连接名称、变量或用户提供的文本（即第二个操作数）的字符串。

实现

SecondOperand

示例

The following code example adds an XMLTask to a package, and sets properties using the TaskHost.

using System;  
using System.Collections.Generic;  
using System.Text;  
using Microsoft.SqlServer.Dts.Runtime;  
using Microsoft.SqlServer.Dts.Tasks.XMLTask;  

namespace XMLTask_API  
{  
    class Program  
        {  
        static void Main(string[] args)  
            {  
                // Set up the objects and tasks.  
                Package pkg = new Package();  
                Executable exec1 = pkg.Executables.Add("STOCK:XMLTask");  
                TaskHost th = exec1 as TaskHost;  
                // You can cast the InnerObject to the XmlTask here.  
                // XMLTask myTask = th.InnerObject as XMLTask;  

                // Create a variable and a FILE connection manager to books.xml.  
                Variable resultVar = pkg.Variables.Add("resultVariable", false, "", "Variable for the result");  
                ConnectionManager connMgr = pkg.Connections.Add("FILE");  
                connMgr.Name = "XMLConnectionManager";  
                // The file, Books.xml, is stored on the C:\ drive.  
                connMgr.ConnectionString = @"c:\books.xml";  

                // Set the XMLTask properties.  
                // The first property to set is the OperationType. Depending on the  
                // OperationType, different properties are valid.  
                // The operation type in this example is VALIDATE.  
                th.Properties["OperationType"].SetValue(th, DTSXMLOperation.Validate);  
                th.Properties["SourceType"].SetValue(th, DTSXMLSourceType.FileConnection);  
                th.Properties["Source"].SetValue(th, connMgr.Name);  
                th.Properties["OverwriteDestination"].SetValue(th, true);  
                th.Properties["SaveOperationResult"].SetValue(th, true);  
                th.Properties["DestinationType"].SetValue(th, DTSXMLSaveResultTo.Variable);  
                th.Properties["Destination"].SetValue(th, resultVar.Name);  
                th.Properties["SecondOperandType"].SetValue(th, DTSXMLSourceType.DirectInput);  
                th.Properties["SecondOperand"].SetValue(th, "<x></x>");  
                th.Properties["ValidationType"].SetValue(th, DTSXMLValidationType.DTD);  
                th.Properties["FailOnValidationFaile"].SetValue(th, true);  
                DTSExecResult valResults = pkg.Validate(pkg.Connections, pkg.Variables, null, null);  
                Console.WriteLine("RESULTS: {0}", valResults);  
            }  
        }  
}  

示例输出：

RESULTS: Success

注解

源文档是第一个操作数。 无论值如何OperationType，此属性都可用于该XMLTask属性。
