[jira] [Created] (THRIFT-5040) Optional fields for struct types are not Nullable in C# (netstd)

Konstantin created THRIFT-5040:
----------------------------------

             Summary: Optional fields for struct types are not Nullable in C# (netstd)
                 Key: THRIFT-5040
                 URL: https://issues.apache.org/jira/browse/THRIFT-5040
             Project: Thrift
          Issue Type: Bug
          Components: netstd - Compiler
    Affects Versions: 0.13.0
            Reporter: Konstantin


Optional fields for struct types are not Nullable in C# (netstd)

 for example 
{code:java}
struct Test {    
1:  required i64 id,
2:  optional bool some_flag
}
{code}
will generate class 
{code:java}
public partial class Test : TBase{  
  private bool _some_flag;
  public long Id { get; set; }
  public bool Some_flag  {    get    {      return _some_flag;    }    set    {      __isset.some_flag = true;      this._some_flag = value;    }  }
{code}
that makes the some_flag to be false even if it was not set on the sending party.

 

The optional struct types should be generated as Nullable<T>:
{code:java}
private bool? _some_flag;
{code}
