How to call a generic extension method with reflection?

Question

I wrote the extension method GenericExtension. Now I want to call the extension method Extension. But the value of methodInfo is alway

Answer 1

Building off of @Mike Perrenoud's answer, the generic method I needed to invoke was not constrained to the same type as the class of the extension method (i.e. T is not of type Form).

Given the extension method:

public static class SqlExpressionExtensions
{
    public static string Table(this IOrmLiteDialectProvider dialect)
}

I used the following code to execute the method:

private IEnumerable GetTrackedTableNames(IOrmLiteDialectProvider dialectProvider)
{
    var method = typeof(SqlExpressionExtensions).GetMethod(nameof(SqlExpressionExtensions.Table), new[] { typeof(IOrmLiteDialectProvider) });

    if (method == null)
    {
        throw new MissingMethodException(nameof(SqlExpressionExtensions), nameof(SqlExpressionExtensions.Table));
    }

    foreach (var table in _trackChangesOnTables)
    {
        if (method.MakeGenericMethod(table).Invoke(null, new object[] { dialectProvider }) is string tableName)
        {
            yield return tableName;
        }
    }
}

where the types defined in _trackChangesOnTables are only known at runtime. By using the nameof operator, this protects against exceptions at runtime if the method or class is ever removed during refactoring.
