Artikel

Executes, in an asynchronous manner, a command that does not return any results beyond an integer value indicating status.

Namespace: Microsoft.VisualStudio.Data.Framework
Assembly: Microsoft.VisualStudio.Data.Framework (in Microsoft.VisualStudio.Data.Framework.dll)

Parameters

command
Type: System.String

The command to be executed.

commandType
Type: Microsoft.VisualStudio.Data.Services.SupportEntities.DataCommandType

A value from the DataCommandType enumeration representing the command type for the indicated command. The value specifies how to interpret the contents of the command parameter.

parameters
Type: array<Microsoft.VisualStudio.Data.Services.SupportEntities.IVsDataParameter[]

A list of parameters to pass with the command.

commandTimeout
Type: System.Int32

Amount of time, in seconds, before which the command times out.

userState
Type: System.Object

The object on which this method calls back as the command progresses.

Implements

IVsDataAsyncCommand.ExecuteWithoutResultsAsync(String, DataCommandType, array<IVsDataParameter[], Int32, Object)

Exceptions

Exception	Condition
ArgumentNullException	The command or the userState parameter is null.
ArgumentOutOfRangeException	The commandTimeout parameter is less than -1.

Remarks

This method performs the same operation as the ExecuteWithoutResults method, but in an asynchronous manner.

If the value of the commandTimeout parameter is 0, there is no timeout (or, timeout is infinite); if the value is -1, the timeout period is that set by the data provider.

The userState parameter uniquely identifies the specific asynchronous operation and is passed back as part of the event arguments for the ExecuteWithoutResultsCompleted event so that a listener can determine which asynchronous process completed.

Note

Other exceptions that occur indicate that the parameter derivation failed for a provider-specified reason.
