c# - 参数比方法更难访问

Question

我正在尝试将列表从一个表单类传递到另一个表单类。这是代码:

List<Branch> myArgus = new List<Branch>();

private void btnLogin_Click(object sender, EventArgs e)
{
    // Get the selected branch name
    string selectedBranch = lbBranches.SelectedItem.ToString();
    for (int i = 0; i < myArgus.Count; i++)
    {
        if (myArgus[i]._branchName == selectedBranch)
        {
            // Open the BranchOverview form
            BranchOverview branchOverview = new BranchOverview(myArgus[i]);
            branchOverview.Show();
        }
        else
        {
            // Branch doesn't exist for some reason
        }
    }
}

然后在我的 BranchOverview 类中:

List<Branch> branch = new List<Branch>();

public BranchOverview(List<Branch> myArgus)
{
    InitializeComponent();

    branch = myArgus;
}

当我运行代码时，出现以下错误:

Inconsistent accessibility: parameter type 'System.Collections.Generic.List<Argus.Branch>' is less accessible than method 'Argus.BranchOverview.BranchOverview(System.Collections.Generic.List<Argus.Branch>)'

你必须声明 Branch 是公开的:

public class Branch {
  . . . 
}
