The IDTSVariableDispenser100 object provided to the component.

Osservazioni

The VariableDispenser is used to read and write variables in the package that contains the component. Before reading or writing a variable, it must be locked using one of the following methods; LockForRead, LockForWrite, LockOneForRead, or LockOneForWrite. After the variables are locked using the dispenser, they are available through the IDTSVariables100 interface.

Esempi

The following example demonstrates how to use the VariableDispenser to lock a single variable, and multiple variables.

// Lock two variables, and then retrieve them by calling GetVariables.
IDTSVariables100 variables = null;

VariableDispenser.LockForRead("variable1");
VariableDispenser.LockForRead("variable2");
VariableDispenser.GetVariables(ref variables);

object variable1 = variables[0].Value;
object variable2 = variables[1].Value;

// Retrieve a single variable.
IDTSVariables100 variables = null;
VariableDispenser.LockOneForRead("variable1", ref variables);

object variable1 = variables[0].Value;

' Lock two variables, and then retrieve them by calling GetVariables.
Dim variables As IDTSVariables100 = Nothing 
VariableDispenser.LockForRead("variable1") 
VariableDispenser.LockForRead("variable2") 
VariableDispenser.GetVariables(variables) 
Dim variable1 As Object = variables(0).Value 
Dim variable2 As Object = variables(1).Value 
Dim variables As IDTSVariables100 = Nothing 
VariableDispenser.LockOneForRead("variable1", variables) 
Dim variable1 As Object = variables(0).Value
