SqlCommand::CommandTimeout Property
Gets or sets the wait time before terminating the attempt to execute a command and generating an error.
Assembly: System.Data (in System.Data.dll)
public: property int CommandTimeout { virtual int get() override; virtual void set(int value) override; }
Property Value
Type: System::Int32The time in seconds to wait for the command to execute. The default is 30 seconds.
Implements
IDbCommand::CommandTimeoutA value of 0 indicates no limit (an attempt to execute a command will wait indefinitely).
Note |
|---|
The CommandTimeout property will be ignored during asynchronous method calls such as BeginExecuteReader. |
CommandTimeout has no effect when the command is executed against a context connection (a SqlConnection opened with "context connection=true" in the connection string).
Note |
|---|
This property is the cumulative time-out (for all network packets that are read during the invocation of a method) for all network reads during command execution or processing of the results. A time-out can still occur after the first row is returned, and does not include user processing time, only network read time. For example, with a 30 second time out, if Read requires two network packets, then it has 30 seconds to read both network packets. If you call Read again, it will have another 30 seconds to read any data that it requires. |
