C# Read Json file into memory and group by same value

I have JSON file:

{
  "DatabaseType": "Customer",
  "TableName": "Test",
  "RowsCopied": "6"
},
{
  "DatabaseType": "Customer",
  "TableName": "JDJD",
  "RowsCopied": "202"
},
{
  "DatabaseType": "Hosting",
  "TableName": "Test",
  "RowsCopied": "6"
},
{
  "DatabaseType": "Logging",
  "TableName": "Test",
  "RowsCopied": "6"
}

I want to group by on based of table name and rows copied.
I think I need to use dictionary inside dictionary.
Let me know if someone can help
