Issue testing null check using NUnit

I am a junior dev that is new to unit testing. My company uses NUnit and I am trying to test a null check in a service method I created. Any idea what my Assert statement should look like if I am trying to test if string acctName = "" ? For some reason string acctName is getting compiler error that says

"The name does not exist in the current context."

MY METHOD:

public Dict getOrder(Client client)
{
    string acctName = client != null ? client.AccountName : "";

    Dict replacements = new Replacement
    {
        {COMPANY_NAME, acctName}
    };
    return new Dict(replacements);
}

MY TEST:

public void getOrderNullTest()
{

    //Arrange

    Client myTestClient = null;

    //Act

    contentService.getOrder(myTestClient);

    //Assert

    Assert.AreEqual(string acctName, "");

}

While you eventually answered your own question and got it to work, know that the issue was that in calling the assert you have Assert.AreEqual(string acctName, "") which has a syntax error, string acctName which is for when you are defining a method, not trying to call it.

Here is another way you could have written it

//Arrange
Client myTestClient = null;
string expectedValue = String.Empty;
string expectedKey = COMPANY_NAME;

//Act
Dict result = contentService.getOrder(myTestClient);

//Assert
Assert.IsNotNull(result);

string actualValue = result[expectedKey];

Assert.IsNotNull(actualValue);
Assert.AreEqual(expectedValue, actualValue);

I ended up writing it like this:

//Arrange

Client myTestClient = null;
string expectedValue = String.Empty;
string expectedKey = COMPANY_NAME;

//Act

Dict actual = contentService.getOrder(myTestClient);

//Assert

Assert.IsTrue(actual.ContainsKey(expectedKey));
Assert.IsTrue(actual.ContainsValue(expectedValue));
