CreationName 属性

Returns the string that the runtime engine gives when it creates an instance of the Variable object and adds the object to the Variables collection. This property is read-only.

IDTSName. . :: . .CreationName

示例

The following example creates a package, adds a ForEachLoop, and adds a variable to the Variables collection of the ForEachLoop. It then retrieves and sets properties on the variable and displays them for viewing, including the CreationName.

static void Main(string[] args)
        {
            Package p = new Package();
            // Add a sequence to the package executables collection
            Sequence seq = (Sequence)p.Executables.Add("STOCK:SEQUENCE");
            // Add a ForEachLoop to the Sequence
            ForEachLoop feLoop = (ForEachLoop)seq.Executables.Add("STOCK:FOREACHLOOP");

            // Add a variable, v, to the variable collection
           // of the ForEach loop.
            Variable v = feLoop.Variables.Add("v", false, "global", 100);

//  Get and set different variable properties

            // Creation Name (read-only)
            String createName = v.CreationName;

            // Description (read/write)
            v.Description = "my new v Description";
            String vDesc = v.Description;

            // ID (read-only)
            String vID = v.ID;

            // Name (read/write)
            String oldName = v.Name;
            v.Name = "my_new_V_name";
            String newName = v.Name;

            String oldNamespace = v.Namespace;
            v.Namespace = "my_new_v_Namespace";
            String newNamespace = v.Namespace;

            // Properties (read-only)
            int pmCount = v.Properties.Count;

            // Qualified Name (read-only)
            String QName = v.QualifiedName;
           
            // RaiseChangedEvent (read/write)

            // Read-only (read/write)
            Boolean vReadOnly = v.ReadOnly;
            v.ReadOnly = true;
            Boolean newVReadOnly = v.ReadOnly;

            // System Variable (read-only)
            Boolean sysVar = v.SystemVariable;

            // Type (read-only)
            TypeCode type = v.DataType;

            // Value (read/write)
            Object vValue = v.Value;
