To call an Oracle procedure from C#, you can use Oracle's data provider for .NET - Oracle Data Provider for .NET (ODP.NET). Here's a simple example of how to call an Oracle procedure from C# using ODP.NET:

  1. Install Oracle's ODP.NET package using NuGet Package Manager in Visual Studio.
  2. Add the reference to Oracle.ManagedDataAccess.dll in your C# project.
  3. Create a connection to your Oracle database using the OracleConnection class:
1
2
string connectionString = "User Id=<username>;Password=<password>;Data Source=<your data source>";
OracleConnection connection = new OracleConnection(connectionString);


  1. Open the connection:
1
connection.Open();


  1. Create a command object to call the stored procedure:
1
2
OracleCommand cmd = new OracleCommand("your_procedure_name", connection);
cmd.CommandType = CommandType.StoredProcedure;


  1. Add parameters to the command if necessary:
1
2
cmd.Parameters.Add("param1", OracleDbType.Varchar2).Value = "value1";
cmd.Parameters.Add("param2", OracleDbType.Int32).Value = 123;


  1. Execute the procedure:
1
cmd.ExecuteNonQuery();


  1. Close the connection:
1
connection.Close();


That's it! This is a simple example of how to call an Oracle procedure from C# using ODP.NET. Make sure to handle any exceptions that may occur during the process and also dispose of your OracleConnection and OracleCommand objects properly to avoid memory leaks.
