+# ContractManagement.GetContractById Method
+
+Maps the specified ID to the deployed contract.
+
+Namespace: [Neo.SmartContract.Framework.Native](../../native.md)
+
+Assembly: Neo.SmartContract.Framework
+
+## Syntax
+
+```c#
+public ContractState GetContractById(int id);
+```
+
+Parameters:
+
+- id: Contract ID. Negative numbers represent native contracts, while positive numbers represent normal contracts (non-native deployed contracts).
+
+## Example
+
+Contract:
+
+```c#
+public class Contract1 : SmartContract
+{
+    public static string MyMethod(int id)
+    {
+        var contract = ContractManagement.GetContractById(id);
+        return contract.Manifest.Name;
+    }
+}
+```
+
+Invoke from neo-cli:
+
+```
+invoke 0x425d355a8a62eebf961884c91c6567d3ff1ab0dc myMethod [{"type":"Integer","value":"-1"}]
+```

+        "type":"ByteString",
+        "value":"Q29udHJhY3RNYW5hZ2VtZW50"
+    }
+]
+```
+
+Response description:
+
+According to the contract code, the contract name associated with the requested ID is returned here.
+
+The string `Q29udHJhY3RNYW5hZ2VtZW50`, when decoded with base64, yields `ContractManagement`.
