本文介绍如何使用 .NET SDK 删除表格存储数据表的单行数据。
前提条件
方法说明
public DeleteRowResponse DeleteRow(DeleteRowRequest request)异步方法：
public Task<DeleteRowResponse> DeleteRowAsync(DeleteRowRequest request)示例代码
以下示例代码用于删除 test_table 表中主键值为 row1 的行数据。
try
{
// 构造主键
PrimaryKey primaryKey = new PrimaryKey
{
{ "id", new ColumnValue("row1") }
};
// 删除行数据时必须配置删除条件 （RowExistenceExpectation.IGNORE，表示不做行存在性判断）
Condition condition = new Condition(RowExistenceExpectation.IGNORE);
// 调用 DeleteRow 方法删除行数据
DeleteRowRequest deleteRowRequest = new DeleteRowRequest("test_table", condition, primaryKey);
DeleteRowResponse deleteRowResponse = client.DeleteRow(deleteRowRequest);
Console.WriteLine($"RequestId: {deleteRowResponse.RequestID}");
Console.WriteLine($"Read CU Cost: {deleteRowResponse.ConsumedCapacityUnit.Read}");
Console.WriteLine($"Write CU Cost: {deleteRowResponse.ConsumedCapacityUnit.Write}");
}
catch (Exception ex)
{
Console.WriteLine($"Delete row failed, exception: {ex.Message}");
}
