Variable.GetPackagePath 方法

定义

命名空间:

Microsoft.SqlServer.Dts.Runtime

程序集:

Microsoft.SqlServer.ManagedDTS.dll

返回变量所属的包的路径。

public:
 virtual System::String ^ GetPackagePath();

public string GetPackagePath ();

abstract member GetPackagePath : unit -> string
override this.GetPackagePath : unit -> string

Public Function GetPackagePath () As String

返回

String

包含包路径的字符串。

实现

GetPackagePath()

示例

以下示例创建一个新包、设置为EnableConfigurationstrue该包并设置该ExportConfigurationFile属性。 然后，该示例向 Variables 集合添加新变量，设置值，并使用 检索包路径 GetPackagePath。 此外，配置将添加到包值的配置集合中 ConfigurationString， ConfigurationType以及 PackagePath。

static void Main(string[] args)  
        {  
            // Create a package and set two properties.  
            Package pkg = new Package();  
            pkg.EnableConfigurations = true;  
            pkg.ExportConfigurationFile(@"C:\conf.xml");  

            // Create a variable object and add it to the   
            // package Variables collection.  
            Variable varPkg = pkg.Variables.Add("var", false, "", 100);  
            varPkg.Value = 1;  
            string packagePathToVariable = varPkg.GetPackagePath();  

            // Create a configuration object and add it to the   
           // package configuration collection  
            Configuration config = pkg.Configurations.Add();  

           // Set properties on the configuration object.  
            config.ConfigurationString = "conf.xml";  
            config.ConfigurationType = DTSConfigurationType.ConfigFile;  
            config.PackagePath = packagePathToVariable;  

            //save the package and its configuration  
            Application app = new Application();  
            app.SaveToXml(@"c:\pkg.xml", pkg, null);  

            //Reload the package  
            Package p1 = app.LoadPackage(@"c:\pkg.xml", null);  
            //Review its Variables collection  
            Console.WriteLine("The value of variable VAR = " + p1.Variables["var"].Value);  
        }  

Shared  Sub Main(ByVal args() As String)  
            ' Create a package and set two properties.  
            Dim pkg As Package =  New Package()   
            pkg.EnableConfigurations = True  
            pkg.ExportConfigurationFile("C:\conf.xml")  

            ' Create a variable object and add it to the   
            ' package Variables collection.  
            Dim varPkg As Variable =  pkg.Variables.Add("var",False,"",100)   
            varPkg.Value = 1  
            Dim packagePathToVariable As String =  varPkg.GetPackagePath()   

            ' Create a configuration object and add it to the   
           ' package configuration collection  
            Dim config As Configuration =  pkg.Configurations.Add()   

           ' Set properties on the configuration object.  
            config.ConfigurationString = "conf.xml"  
            config.ConfigurationType = DTSConfigurationType.ConfigFile  
            config.PackagePath = packagePathToVariable  

            'save the package and its configuration  
            Dim app As Application =  New Application()   
            app.SaveToXml("c:\pkg.xml", pkg, Nothing)  

            'Reload the package  
            Dim p1 As Package =  app.LoadPackage("c:\pkg.xml",Nothing)   
            'Review its Variables collection  
            Console.WriteLine("The value of variable VAR = " + p1.Variables("var").Value)  
End Sub  

示例输出：

变量 VAR = 1 的值
