GetItemRequest Class

Container for the parameters to the GetItem operation.

The GetItem operation returns a set of attributes for the item with the given primary key. If there is no matching item, GetItem does not return any data.

GetItem provides an eventually consistent read by default. If your application requires a strongly consistent read, set ConsistentRead to true . Although a strongly consistent read might take more time than an eventually consistent read, it always returns the last updated value.

Syntax

public class GetItemRequest : AmazonWebServiceRequest
         IRequestEvents

Examples

This example shows how to get an item in a table.

GetItem sample

// Create a client
AmazonDynamoDBClient client = new AmazonDynamoDBClient();

// Define item key
//  Hash-key of the target item is string value "Mark Twain"
//  Range-key of the target item is string value "The Adventures of Tom Sawyer"
Dictionary<string, AttributeValue> key = new Dictionary<string, AttributeValue>
{
    { "Author", new AttributeValue { S = "Mark Twain" } },
    { "Title", new AttributeValue { S = "The Adventures of Tom Sawyer" } }
};

// Create GetItem request
GetItemRequest request = new GetItemRequest
{
    TableName = "SampleTable",
    Key = key,
};

// Issue request
GetItemResult result = client.GetItem(request).GetItemResult;

// View response
Console.WriteLine("Item:");
Dictionary<string, AttributeValue> item = result.Item;
foreach (var keyValuePair in item)
{
    Console.WriteLine("{0} : S={1}, N={2}, SS=[{3}], NS=[{4}]",
        keyValuePair.Key,
        keyValuePair.Value.S,
        keyValuePair.Value.N,
        string.Join(", ", keyValuePair.Value.SS ?? new List<string>()),
        string.Join(", ", keyValuePair.Value.NS ?? new List<string>()));
}
