SecondOperand 属性

Gets or sets the name of the connection, the variable, or the user-provided text that is the second operand in an operation that uses two operands. The second operand may be an XML document, a DiffGram, an XSLT, an XPath, or a validating document, depending on the operation.

用法
Dim instance As XMLTask
Dim value As String

value = instance.SecondOperand

instance.SecondOperand = value

public string SecondOperand { get; set; }

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

abstract SecondOperand : string with get, set
override SecondOperand : string with get, set

final function get SecondOperand () : String
final function set SecondOperand (value : String)

属性值

类型：System. . :: . .String
A String that contains the name of the connection, the variable, or the user-provided text that is the second operand.

实现

IDTSXMLTask. . :: . .SecondOperand

注释

The source document is the first operand. This property is available to the XMLTask, regardless of the OperationType value.

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);
            }
        }
}

Sample Output:

RESULTS: Success
