Anonymous method cannot have 'params' parameter

• Jun 26, 2019

CodeRush Classic shows the Anonymous method cannot have ‘params’ parameter code issue if an anonymous method includes a params parameter.

Fix

Use a usual parameter of an array type instead of the params parameter.

Purpose

Highlights the anonymous method declarations, which would cause the params is not valid in this context compilation error.

Example

C#

delegate void MyDelegate(string[] data);
public void TestMethod()
{
    MyDelegate mDel = delegate(params string[] │data) 
    {
        foreach(string str in data)
            Console.WriteLine(str);
    };
}

Fix:

C#

delegate void MyDelegate(string[] strings);
public void TestMethod()
{
    MyDelegate mDel = delegate(string[] data) 
    {
        foreach(string str in data)
            Console.WriteLine(str);
    };
}
