API Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

.NET Framework 3.5
 
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.

Namespace: Amazon.DynamoDBv2
Assembly: AWSSDK.dll
Version: (assembly version)

Syntax

C#
public virtual GetItemResponse GetItem(
         GetItemRequest request
)

Parameters

request
Type: Amazon.DynamoDBv2.Model.GetItemRequest

Container for the necessary parameters to execute the GetItem service method.

Return Value
Type: Amazon.DynamoDBv2.Model.GetItemResponse
The response from the GetItem service method, as returned by DynamoDB.

Exceptions

ExceptionCondition
InternalServerErrorException An error occurred on the server side.
ProvisionedThroughputExceededException Your request rate is too high. The AWS SDKs for DynamoDB automatically retry requests that receive this exception. Your request is eventually successful, unless your retry queue is too large to finish. Reduce the frequency of requests and use exponential backoff. For more information, go to Error Retries and Exponential Backoff in the Amazon DynamoDB Developer Guide.
ResourceNotFoundException The operation tried to access a nonexistent table or index. The resource might not be specified correctly, or its status might not be ACTIVE.

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
var result = client.GetItem(request);

// 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>()));
}
